Now you don’t have to wait months to find out whether you are going to become a mother or not. You can now confirm it by taking a home pregnancy test before your period or within a day or two of missing your period. This is what doctors call an ‘early detection test’. In simple words, it is a way to know the news of the baby in advance.

When a woman becomes pregnant, her body starts producing a special hormone called hCG. This hormone is only found in the body when she is pregnant. When you take a pregnancy test with a kit, the kit looks for this hormone in your urine. If it is found, the result is positive.

How does an early detection pregnancy test work?

Early detection pregnancy test actually detects a special signal inside your body. Simply put, it monitors a hormone produced in your body.

The simple steps to work are given below:

Detecting hCG hormone: When you are pregnant, your body starts producing a hormone called hCG (human chorionic gonadotropin). This hormone is only produced when the baby implants in the uterus. The job of this kit or stick is to detect that hormone in the urine.

Changing color like hemoglobin: A special type of chemical is given in that narrow part or window-like area of ​​the pregnancy kit. When you urinate there, if that special hormone is present in it, the chemical mixes with it and creates a colored stain.

Why is it called ‘early’ or ‘early’? Normal test kits only work when the amount of hormone in the body increases a lot. But ‘early detection’ kits are so powerful that they can sense even a very small amount of hormone in the body. So they can give the right news a few days before your period.

The secret of the two lines: There are two types of antibodies inside the kit. The first one changes color if the hormone is present and the second one changes color only to make sure that the kit is working properly (which we call the control line). So the appearance of two lines means that you have that hormone in your body.

An important tip: Since it works with very small amounts of hormone, if you drink a lot of water during the test, the hormone gets diluted in the urine. Then the kit may not be able to detect it properly. So it is best to test with the first urine of the morning.

H2: How many days before can you take this test

If you can’t wait until your period is due, then this ‘early detection’ test is a great way for you. Usually, regular test kits work after your period is missed, but with these special kits, you can test even earlier.

I’ll explain the timing below in simple terms:

4-5 days before your period: There are several high-quality early detection kits (such as Clearblue or other well-known brands) that can give results 4 or 5 days before your expected period or menstruation.

10-12 days after intercourse: If you remember the exact day you had intercourse, you can take this test 10 to 12 days after that day. Because it takes at least this much time for hormones to be produced after the baby is implanted in the uterus.

The most accurate time: Although you can take the test 5 days before, doctors recommend taking it at least 1 or 2 days before your period. This greatly reduces the chance of error and makes the spot clearer.

A small caution:

If you test 5 days before your period and the result is ‘negative’ (one spot), don’t be discouraged. It may be that your body hasn’t produced enough hormones yet. If that’s the case, wait until your period is due and test again. Sometimes, a few days late can give you the real result.

What can happen if you test too early?

Many people are so eager to know about the baby that they test two to three days after intercourse. But if you do it too quickly, there can be some confusion that will put you under unnecessary tension.

What can happen if you test too quickly:

False Negative: This is the most common. You may be pregnant but your body has not yet produced enough hCG hormone. The kit cannot detect the hormone and shows a spot. You think the result is negative, but if you test a few days later, it might have been positive.

Very faint or light spot: If you test too early, the second spot on the kit is so light that it is not visible to the naked eye. This leaves a feeling of confusion in your mind as to what really happened?

Unnecessary tension: Once you see the result is negative, you feel upset. This mental stress is not good for the body at all. But if you had waited just 3-4 more days, you might have gotten the sure news.

Waste of money: The price of each early detection kit is a little higher than the regular kit. If the result is not clear after testing too early, you will have to buy a new kit again, which is actually a waste of money.

My simple advice: If you are in a hurry, be patient at least until 3 days before your period. And if you see the spotting is very light even after getting the positive news, don’t get upset and test again after 48 hours or two days. Because the amount of this hormone in the body doubles every two days, then the result will be completely clear.

Why is morning urine considered better

When it comes to pregnancy tests, everyone says “test with the first urine of the morning.” But this is not a superstition, there is a very clear reason behind it. Simply put, morning urine is the most ‘thick’ or ‘strong’.

Why is morning urine the best?

Hormone levels are high: When you are pregnant, the hCG hormone that is produced in your body is excreted through urine. When you sleep all night (about 6-8 hours), you do not drink water and do not urinate. As a result, the urine is stored in the bladder for a long time and the amount of hormone in it increases a lot.

Easy to detect: During the day, we drink water, tea or coffee repeatedly. This dilutes the urine. When the urine is diluted, the hormone also mixes with it and becomes lighter. Then the test kit does not detect that hormone properly. But since the hormone is completely concentrated in the first urine of the morning, the kit recognizes it very easily.

Less risk of error: At the very beginning of pregnancy (when it has only been a few days), the hormones in the body are very low. In that case, if you test during the day, there is a risk of getting a ‘negative’ result by mistake. But that risk is much less with morning urine.

What if you forget to test in the morning? If for some reason you cannot test in the morning, then do not drink water for at least 3 to 4 hours and then test. This will make the urine a little thicker and increase the chances of getting a good result.

What does faint line mean?

Often, one line is very dark red in pregnancy kits, but the second line is very light or blurry. Seeing this faint line can make you wonder if it is positive or negative?

In simple terms, understand its meanings:

1. You are pregnant (most common): A second line on the kit means that the hCG hormone has been found in your body. A faint line means that you are pregnant but the pregnancy is very early. The amount of hormone in your body is still very low, so the kit cannot show it very clearly.

2. Testing too early: If you test long before your period or very few days after intercourse, you will see such a faint line. If you test two or three days later, you will see that this line has become very dark.

3. Diluted urine: If you test after drinking a lot of water, the hormone becomes diluted. As a result, the line may not be very clear and may be light or blurry.

4. Evaporation Line: This is not positive. If you see the result much later than the time written on the kit package (such as 5 minutes), the urine may dry out and a dark or gray shade may appear there. Do not mistake this for a real spot.

What should you do now if you see a faint spot?

Wait 48 hours: The hormone doubles every two days during pregnancy. So if you see a light spot today, test again with your first morning urine exactly two days later. You will see that the spot is much darker than before.

Test in the morning: Test with your first urine tomorrow morning instead of at another time of the day.

Doctor’s advice: If the spot is light even after testing two or three times, go to the lab and get a Blood Test (Beta hCG). A blood test gives absolutely sure results.

H2: How reliable is early detection pregnancy test? Many of us rely on pregnancy kits a lot, but we must remember that it is a device. Early detection tests usually give up to 99% accurate results, but it depends on when and how you do the test.

The actual calculation of reliability is given below:

After missed period: If you test at least 1 day after your period or menstrual date, these kits give almost 100% accurate results. Then there is almost no chance of error.

Before missed period: If you test 4-5 days before your period, the reliability decreases slightly (about 60-75%). This is because hormones do not increase at the same speed in everyone’s body. Some may get the news early, while others may get it a little late.

Kit quality: Not all kits in the market are the same. Expensive kits from good brands can detect very subtle hormones, which ordinary or cheap kits may not. Therefore, reliability also depends to some extent on the quality of the kit.

Correct usage: If you do not follow the instructions on the packet (for example, urinating too much or reading the result after 10 minutes instead of 5 minutes), the kit may show you the wrong result.

When can the result be wrong?

1. Drug effects: If you have already taken any hormone injections or special drugs to conceive a child, the result may come out ‘positive’ even if you are not pregnant. 2. Expired kit: If the kit has expired, it is not reliable at all.

My advice: No matter what the result of the kit comes out, it is always most reliable to go to the doctor and get a blood test or an ultrasound to be completely sure.

What mistakes should be avoided?

Sometimes, due to minor mistakes, the correct result cannot be obtained due to some mistakes while taking a pregnancy test. So that you do not get unnecessarily worried, it is very important to avoid these common mistakes:

1. Drinking too much water

Many people think that drinking more water will make you urinate more and make the test easier. But this is a big mistake. Drinking too much water dilutes the urine, which reduces the concentration of the hCG hormone. This can cause the result to be ‘negative’ even though you are pregnant.

2. Seeing the result before the right time or seeing it too late

The kit package usually asks to wait 2 to 5 minutes. Many people get impatient and throw the kit away after 1 minute. Again, many people want to check the result after 1 hour.

Remember: The light spot that appears on the kit after a long time is called an ‘evaporation line’, which is not a real pregnancy.

3. Not seeing the expiration date of the kit

When buying a kit from a store, be sure to check its expiration date. The chemicals in an expired kit no longer work, so there is a high chance of getting an incorrect result.

4. Putting too much or too little urine in the dropper

Usually 2-3 drops of urine are added to the specific hole on the kit. If you pour too much urine, the kit may get wet and get ruined. If you pour too little, the chemical reaction will not take place properly.

5. Using a dirty container

You must use a clean and dry container to collect urine. If there is soap or water residue, the results may be messed up.

A special tip: If you drink too much tea or coffee at night, it is better to not eat anything for a few hours before testing with the first urine of the next morning.

When should you test again if you get a negative result?

A negative result in an early detection test does not always mean that you are not pregnant. Sometimes, it takes a few days for the body to produce enough hormones.

Correct steps to take after a negative result:

Wait at least 3 days: If you get a negative result before your period is due, wait for at least 3 to 4 days. Then test again. During this time, the hCG hormone level in the body increases significantly, so the result is likely to be accurate.

Wait until you miss your period: It is best if you wait until your period or period is due. Testing after a missed period gives the most accurate results.

Test in the morning: If you test at a different time of the day for the first time and it comes out negative, then the next time you should definitely test with your first urine in the morning.

What if you get a negative result again but don’t get your period?

If you see that even after several tests, you are still getting negative results but your period is not starting, don’t just sit at home. There may be other reasons behind this (such as hormonal problems or stress). In such a situation, it is important to consult a gynecologist or doctor and go to a lab for a blood test.

What to do next after getting positive

Getting two lines or a positive result on a pregnancy test is the beginning of a new chapter in your life. It is normal to feel happy at this time, but along with emotions, some urgent steps need to be taken so that both you and your unborn child are healthy.

What to do after the result is positive:

Make a doctor’s appointment: The first thing to do after getting a positive result is to see a gynecologist or an experienced doctor. He will calculate the estimated due date (EDD) of the baby according to the date of your last period (LMP) and do some necessary preliminary tests (such as an ultrasound).

Start folic acid: Doctors usually recommend taking folic acid tablets from the very beginning of pregnancy. It helps in maintaining the structure of the baby’s brain and spine. If you have not taken it before, start taking it as soon as possible after consulting a doctor.

Make lifestyle changes: *

  •  Avoid lifting heavy objects or doing excessive physical work.
  • If you have a habit of smoking or drinking alcohol, completely avoid it.
  • Reduce the amount of tea or coffee you drink.

Be careful before taking medicine: The medicines that we take for a common headache or gas can be harmful to the fetus during pregnancy. So do not take any medicine without consulting a doctor.

Nutritious food and plenty of water: Drink plenty of water from now on and make a habit of eating a balanced diet (vegetables, fruits, milk, eggs).

A special tip:

Many times, even if the home test comes out positive, doctors recommend going to the lab and doing a blood test (Beta hCG) to confirm the pregnancy 100%. So do not panic, this is just a confirmation process.

Why body symptoms are important without tests

Pregnancy kits or lab tests certainly give you sure news, but your body is the biggest signal provider. Many times it is seen that the test kit results are negative, but the body’s symptoms say that you are going to become a mother. Why it is important to give importance to these symptoms is given below:

Why the body speaks first:

The first effect of hormones: The body’s hormones start changing rapidly after the fetus settles in the uterus. Due to these hormonal changes, your mood, appetite or body strength changes before they are detected in the urine.

Helps to calculate: Many times, if your period is irregular, it is not clear when exactly you should test. Then, by seeing the body’s symptoms (such as breast tenderness or nausea), you can understand that now is the right time to test.

Recognize the danger signs: Sometimes, mild lower back pain or spotting (light bleeding) may occur in early pregnancy. By paying attention to the symptoms, you will be able to understand whether it is normal implantation bleeding or a sign of danger that requires a quick visit to the doctor.

Mental preparation: When you start to understand the symptoms of your body, you unknowingly start to walk carefully, do not lift anything heavy or take over-the-counter medications. This precaution plays a big role in the safety of your future child.

Some common symptoms of early pregnancy:

1. Chest heaviness or pain: This is slightly different from the pain before your period and lasts longer. 2. Excessive fatigue: Feeling sleepy all day or feeling very weak for no reason. 3. Frequent urination: Due to hormones, blood flow to the uterus increases, so you may have to go to the bathroom repeatedly. 4. Sensitivity to smells: Suddenly feeling nauseous at the smell of food or perfume.

Conclusion

Early Detection Pregnancy Test is a modern and reliable way to confirm pregnancy. But remember that taking care of your own body is more important than a test result. Whether the result is positive or negative, it is most important to be aware of your physical changes and stay calm during this time.

Be patient: If the result is negative before your period is missed, do not get upset and test again after a few days. Give your body some time to produce hormones.

Follow the correct method: Always use first morning urine to avoid false results and follow the instructions on the kit.

Pay attention to the symptoms: Test kits can be wrong many times, but do not ignore the body’s symptoms (such as fatigue or nausea).

Pelvic pain third trimester causes and best natural remedies for pregnant mothers

“Pelvic pain third trimester” is a very common issue for pregnant women, but simple steps and exercises can provide quick relief naturally.

The last three months of pregnancy or the third trimester is a special time of joy for every mother. 

pelvic pain third trimester

However, along with this joy, some new problems also start to appear in the body. Especially towards the end, many mothers and sisters start experiencing a kind of heavy and uncomfortable pain around the waist, lower abdomen and groin.

Many mothers and sisters in the village consider this problem normal and tolerate it with their mouths closed. But if you are a little aware and follow some simple rules, this pain can be reduced to a great extent. If the mother’s body is healthy, the baby in the womb will also be healthy, so it is most important to take care of yourself in these last days.

What is the real cause of pelvic or lower abdominal pain in the last three months? 

By the end of pregnancy, the uterus of mothers becomes very large. As a result, it is very normal to have pressure on the lower abdomen. However, some specific physical changes are behind the severe pain or biting sensation that occurs in the joints of the lower abdomen during this time.

Many mothers want to know from us, why did you suddenly start having so much pain in your waist and groin at this time? 

The main reason for this is that Allah Almighty has created our body in such a way that the mother’s path is easy during childbirth. And for this reason, some of the veins and bone joints inside the body start to soften.

The effect of the relaxin hormone and changes in the body’s balance 

During pregnancy, a special hormone or juice called relaxin is produced in the mother’s body. The function of this hormone is to loosen and soften the bone joints of the pelvic region, i.e. the lower part of the waist.

Many mothers feel that “pelvic pain third trimester” is shifting or increasing when they try to walk or sit.

Because these bones are soft, mothers feel severe pain while walking or moving around in bed.

Baby weight gain and extra pressure on the uterus

In the last three months, the baby in the womb starts to grow very quickly and its weight increases. As the baby slowly starts to descend, the entire pressure of its head falls on the mother’s pelvis or pelvic bones.

Pregnancy changes the whole body structure and “pelvic pain third trimester” develops mainly due to this heavy pressure on the pelvic floor.

Because of this extra weight, mothers find it very difficult to sit, stand or even walk a little.

Pubic symphysis dysfunction or SPD

This is a major cause of pelvic pain. The place where the bones on both sides of our abdomen meet is called the pubic symphysis. If this joint becomes too loose during pregnancy, even moving your legs slightly can cause a stabbing pain in the groin.

Round ligament strain or muscle spasm  

As the uterus grows, the ligaments that hold the abdomen in place put extra strain. Especially when you get up suddenly from bed or cough, you may experience a whip-like pain on one side of your lower abdomen.

What mistakes do village mothers make at home during this pain? 

There is a trend in our village that whenever pregnant mothers experience any pain, they are told, ‘It’s nothing, just bear it.’ Many times, mothers massage or apply heat incorrectly to reduce pain, which can cause harm to the unborn child.

Another big mistake is that many mothers lie in bed all day due to pain. If they do not move at all, the blood circulation in the body decreases and the muscles become stiffer. As a result, the pain increases many times more than it decreases.

Standing continuously or lifting heavy objects 

Village mothers have to do a lot of household work, such as fetching water, threshing rice or lifting heavy buckets. At this late stage, bending down suddenly or lifting something heavy can cause serious injury to the pelvic bone joints.

Expert doctors state that “pelvic pain third trimester” worsens instantly when a pregnant woman lifts any heavy object.

So you should stay away from any heavy work during this time.

Wrong sleeping and sitting habits

Many people sleep on their backs or sit hunched over while sitting. When you sleep on your back, the entire weight of the uterus falls on the large blood vessels in the back, which also prevents the baby from getting oxygen.

You must avoid wrong sitting postures because “pelvic pain third trimester” can be reduced simply by maintaining a straight back.

While sitting, you should always sit upright with a soft pillow or cushion behind your back.

Simple household chores and rulesHow to do them and their benefits
Sleeping on your backSleeping on your left side with a soft pillow between your legs reduces pressure on your bones.
Warm compressApplying a warm water bag to the back of the waist or lower abdomen for 10 minutes can provide relief.
Pelvic Support BeltSpecial belts are available in the market for pregnant mothers, which help to hold the extra weight of the abdomen.

Light exercise and ways to strengthen the muscles of the pelvic area

In the last days, it is better to take a light walk inside the house without lying down at all. In addition, ‘Kegel exercise’ or pelvic floor exercise is very beneficial for this pain. 

You have to hold the lower muscles for 5 seconds as if you are holding back urine and then release them. Doing this several times a day strengthens the muscles in that area.

Using the right shoes and rules for climbing stairs

At this time, heels or high shoes should not be worn. You should wear very soft and even shoes. You should take your feet one by one very carefully while climbing stairs. 

If you follow these daily movement tips carefully, “pelvic pain third trimester” will remain under control naturally. There should be no rush.

When will you understand that this pain is not normal and you should go to the doctor?

In the last three months of pregnancy, not all pains can be cured with simple or home remedies. Sometimes, there may be signs of a major danger hidden behind this pelvic pain, which our village mothers often do not understand.

So, doesn’t the question arise in your mind that when will I understand whether this pain is causing any harm to the baby? 

Yes, if the pain is accompanied by shivering and fever, or there is a severe burning sensation and foul odor during urination, then you should understand that there is an infection inside.

Signs of premature labor pain or preterm labor

If you feel that there is a specific time or rhythm of the pain—for example, the lower abdomen tightens and hurts every 10 minutes and the waist is pinching from the back, then this may be a sign of labor pain.

Regular physical checking is essential because “pelvic pain third trimester” could sometimes blend with early labor contractions.

Neglecting this condition can lead to premature birth, which is very risky for the baby.

Signs of bleeding or water breaking

If a small amount of blood is seen with severe pain in the lower abdomen or groin, or if the water suddenly starts leaking through the vagina or breaking in large quantities at once, then you should not stay at home for even a second.

Medical emergency arises if “pelvic pain third trimester” is accompanied by any kind of vaginal bleeding.

This can be a sign of the placenta or the placenta becoming loose.

Sudden decrease in baby’s movements-

If the normal movements of the baby in the stomach (at least 10-12 times a day) suddenly decrease or seem to stop altogether along with the intensity of the pain, then it is a sign of lack of oxygen in the baby.

Excessive headache and body swelling – 

If the pain is accompanied by sudden blurring of vision, severe headache, and excessive swelling of the hands, feet, and face, then it is a major symptom of eclampsia or high blood pressure.

Responsibilities of family members during this difficult time of pregnancy and some important advice

The family has the most important role in relieving the physical pain of the pregnant mother. Especially the men of the house and the mothers-in-law should be extra careful towards the mothers during this time. If the mother is in a good mood and free from worries, many physical pains can be easily tolerated.

For your convenience, the things that the family members can do for the well-being of a mother are summarized in points below:

  • Comfort: The mother should be kept completely away from difficult tasks like lifting heavy buckets, folding clothes or bending down to wipe the house.
  • Food: Calcium and vitamin-rich foods such as milk, eggs, small fish and enough vegetables should be included in the daily diet.
  • Rest: After cooking in the afternoon, arrangements should be made so that the mother can sleep peacefully for at least two hours and at least eight hours at night.
  • Mentality: The mother should always be treated well and courage and mental strength should be provided to overcome the fear of childbirth.

How village mothers should prepare for the days of delivery in advance

In the last three months, when the pain in the waist and lower abdomen indicates that the time of the baby’s arrival is approaching, it is good to make some preparations from then on. If there is a sudden problem at night in the village, it is difficult to get a car or a doctor.

So, you should get a good midwife or midwife and the hospital number in case of emergency.

If you plan your hospital journey in advance, “pelvic pain third trimester” won’t cause extra mental panic during delivery.

It would be wise to make arrangements for a blood donor in advance, according to your money and blood group.

Some special advice from an experienced doctor that mothers need to know

Sometimes, mothers are afraid to go to the doctor or do not open up about their pain out of shame. But if you follow the doctor’s advice, this last period can be very relaxing.

Doctors always say, never sit with one leg on the other during this time.

Clinical reports show that “pelvic pain third trimester” can be greatly reduced by resting your feet flat on the floor while sitting. When getting out of bed, always tilt to one side first, then slowly rise up on your hands. Standing up suddenly can cause severe tension in the abdominal muscles.

Conclusion

The pelvic or lower abdominal pain of the last three months of pregnancy or the third trimester is a familiar experience for every expectant mother. This is mainly due to the changes in hormones inside the body and the weight gain of the fetus. 

The ordinary and simple mothers and sisters of our village often endure this pain silently, which is not right at all. A little awareness, following the correct rules of lying down, light Kegel exercises and a little extra love and support from family members can make these difficult days much easier and happier. 

However, if any symptoms like water breaking, blood appearing or the baby’s movements decreasing appear outside of the normal pain, then you cannot sit at home hoping for any poetic treatment or cure. In that situation, you should quickly take the child to a government hospital or an experienced doctor. Only if the mother is healthy will our future children see the light of day in a healthy way. Therefore, it is our responsibility to pay maximum attention to the body of every mother in these last days.
