When Is the First Trimester OverAfter the journey of pregnancy begins, every mother eagerly waits to pass the first stage or the first trimester. This is the most important and sensitive period of pregnancy, where the baby’s major organs are formed.

Passing this period means a significant reduction in the risk of miscarriage and a glimpse of relief from the uncomfortable symptoms of pregnancy. Knowing exactly when the first trimester ends and what changes occur in the body after that, you can mentally prepare for the next stage.

How many weeks does the first trimester last

When Is the First Trimester Over pregnancy usually lasts from 1 to 13 weeks (13 weeks and 6 days). According to medical calculations, this calculation start from the first day of your last menstrual period (LMP). Although many people call the first three months as calendar months, doctors give more importance to the calculation of week to understand the correct progress of pregnancy. In these less than 14 weeks, the embryo gradually takes the form of a complete little human being from a single cell, whose arms, legs and major organs are formed. Entering the 14th week means that you have entered the second or intermediate stage of your pregnancy.

1 to 4 weeks: This is when conception occurs and the embryo implants in the uterus. Most mothers can tell when their period stops by the end of the 4th week.
5 to 8 weeks: This stage is very important because during this time the baby’s heart starts beating and the brain and spinal cord are formed.
9 to 12 weeks: At this time the fetus is called a ‘fetus’. Its fingers, toes and mouth begin to become clear. At the end of 12 weeks, the baby’s kidneys start working and urine is produced.
13 weeks: This is the last week of the first trimester. During this time, the baby’s bones start to harden and the placenta or womb takes over responsibility of providing complete nutrition.
Duration varies: Many hospitals or experts also consider the end of the first stage at the end of 12 weeks, but internationally the period up to 13 weeks and 6 days is considered the first trimester.

Why is the 12th week considered the end?

Although in medical science, When Is the First Trimester Over 13 weeks to 6 days is called the first trimester, in common parlance or in many clinics, 12 weeks is considered a major milestone because during this period, all the major organs of the baby’s body (such as the heart, lungs, kidneys and brain) are fully formed. The end of 12 weeks means that the baby has completed the embryo or ’embryo’ stage and has now emerged as a full-fledged ‘fetus’. In addition, the biggest concern of pregnancy, i.e. the risk of miscarriage, decreases by about 65% to 80% after 12 weeks. This is why many couples do not want to tell others about the pregnancy before 12 weeks and consider this time as a psychological end to the first stage.

The main reasons for considering 12 weeks as the end are given below:

Completion of organ formation: By 12 weeks, all the important structures of the baby’s body are formed, the next period is just the time for those organs to grow in size and mature.
Placental control: From this time on, the placenta becomes fully functional and takes over the responsibility of producing hormones and providing nutrition to the baby, which make the pregnancy more stable.
Reduced risk of miscarriage: Statistics have shown that the chances of a successful pregnancy increase significantly after successfully completing 12 weeks.
Physical changes: In most pregnant women, uncomfortable symptoms like morning sickness or nausea and extreme fatigue start to decrease after 12 weeks.
Important scans: Around 12 weeks, the ‘NT Scan’ or the first major ultrasound is done, which confirms the baby’s well-being and whether there are any birth complications.
Emotional relief: This is a psychological milestone for mothers because from then on they start enjoying the pregnancy more and the existence of the baby in the stomach becomes clear.

The 12th week meansWhen Is the First Trimester Over you have passed the most challenging period of pregnancy. Many mothers see this period as the beginning of the “honeymoon period”, as the inexplicable fatigue and nausea of the first trimester begin to fade. Your body’s hormone levels are now somewhat stable and your belly is starting to show a slight “baby bump” as your uterus rises above your pelvic area. This is a time of rapid growth for your baby; every little organ in his body is now functioning and he can now move around inside the womb (although you may not feel it for a few more weeks). This is a time when you start to get over the physical discomfort and start to truly enjoy your pregnancy.

The main changes that can be observed after 12 weeks are:

Return of energy: Your energy levels will start to increase and the lethargy or tendency to sleep all day in the first trimester will decrease.
Relief from morning sickness: In most women, nausea and severe aversion to food decrease and normal appetite returns.

Reduced frequency of urination: As the uterus rises, the pressure on the bladder decreases slightly, which may temporarily reduce the need to go to the bathroom frequent.
Skin and hair changes: Due to the effects of hormones the skin appears to have a kind of glow (Pregnancy Glow) and many people’s hair becomes thicker and shinier than before.
Baby’s movement and development: The baby’s fingernails are formed and he can now move his hands and feet. He even starts sucking his thumb now.
Emotional relief: As the risk of miscarriage is significantly reduced, the mother’s stress decreases and confidence about the pregnancy increases.

What are the symptoms towards the end of the first trimester

The last days of the first trimester are a time of transition. During this time, your body prepares itself for the second trimester. Although nausea may start to subside compared to the previous weeks, some new symptoms may appear due to hormonal changes. Your uterus is now the size of a large lemon or orange, which can cause a slight tightening in the lower abdomen. During this time, your blood circulation increases by about 50%, which may cause your heart rate to increase slightly and your skin to have a special glow or ‘pregnancy glow’. When Is the First Trimester Over time when the external changes in your body gradually begin to be visible to others.

Common symptoms towards the end of the first trimester:

Increased appetite: As nausea subsides, your appetite will return and you may feel hungry more often.
Excess white discharge (Leukorrhea): The increase in estrogen hormone can cause increase in thin, white and odorless vaginal discharge which protects the uterus from infection.
Dizziness or lightheadedness: You may feel dizzy or weak at times due to changes in blood pressure and dilation of blood vessel.
Breast changes: The size of the breasts continues to increase and the areola (the area around the areola) begins to darken and become larger.
Mild abdominal discomfort or gas: The progesterone hormone slows down the digestive process, which can cause bloating or gas problem.
Mood changes: Hormonal fluctuations as the trimester changes can cause your mood or ‘mood swings’.

Does it end at the same time for everyone?

According to medical science, the first trimester ends at 13 weeks and 6 days for everyone, but in reality, each woman’s experience and pregnancy symptoms can vary at different times. Essentially, “trimester” is a calendar-based division that makes it easier for doctors to track the progress of pregnancy. But your body doesn’t follow a specific date or clock. For example, morning sickness or nausea may go away right after 12 weeks, while for others it may last until 14 or 15 weeks. So while the math is the same for everyone, the physical and hormonal changes you feel will manifest themselves at different times for each person.

Why this period feels different for each person:

Hormonal variations: Each body reacts differently to the hormones progesterone and hCG, so the time it takes for symptoms to subside can vary.
Accurate Date Calculation: Sometimes there is uncertainty about the exact date of conception so ultrasound reports may be a little off in terms of weeks.
Previous Pregnancy: Second or third-time mothers often experience faster relief from first-trimester symptoms or experience physical changes earlier.
Uterine Position and Size: Depending on the mother’s body structure and the position of the uterus, the time when the “baby bump” or belly size becomes visible is not the same for everyone.
Physical Condition: The mother’s weight, diet, and general health can affect the experience of entering the second trimester from the first trimester.

When to be careful

Passing the first trimester of pregnancy meansWhen Is the First Trimester Over decreased but this does not mean that caution can be relaxed. Sometimes, even if some physical symptoms seem normal, they can be a sign of a major complication. It is normal to feel mild tension, especially as the uterus grows, but if the pain is severe or accompanied by any other abnormality, it is a matter of concern. In addition, ignoring sudden changes in blood pressure or signs of infection can hinder the growth of the baby. Your body constantly gives you signals during pregnancy; being able to read those signal correctly and taking timely action is the main responsibility of a conscious mother.

It is important to be alert immediately if the following symptoms occur during your pregnancy:

Vaginal bleeding: Light spotting or bright red bleeding can be a sign of miscarriage or placental problems.
Severe lower abdominal pain: If there is severe twisting pain on one side of the abdomen or the entire lower abdomen that does not subside even with rest.
Excessive nausea: If you are unable to keep any food or water down due to vomiting, which can lead to dehydration.
High fever and chills: A fever of more than 100.4 degrees Fahrenheit indicates an infection which can affect the development of the fetu.
Burning during urination: This can be a sign of a urinary tract infection (UTI), which needs to be treated promptly during pregnancy.
Abnormal vaginal discharge: If the discharge smells bad, is green or yellowish in color, or is excessively itchy.

Sudden weight loss: You should gain a little weight by the end of the first trimester, but if you are losing a lot of weight, tell your doctor.

the end of the first trimester, your body starts to stabilize relatively. Since the baby’s bones and muscles are formed rapidly from this time, it is important to increase the level of calcium, protein and iron in your diet. Now that nausea has subsided, you can easily consume balanced meals. In addition, you should start light exercise or regular walking to increase blood circulation and keep your body flexible during this time. Maintaining mental peace and drinking enough water will help keep your skin glowing and your digestive system in order. When Is the First Trimester Over is called the ‘golden period’ of pregnancy, so prepare yourself for the next stage by utilizing this time proper.

How to take care of yourself after entering the second trimester:

Nutritious diet: Include milk, yogurt, cheese, eggs, lean meat and lots of green vegetables in your diet. The baby’s bone formation now requires a lot of calcium.
Regular exercise: Walk slowly for at least 20-30 minutes every day or do pregnancy yoga as per the doctor’s advice. This will increase your blood circulation and reduce back pain.
Iron and folic acid: Take regular iron and calcium supplements as per the doctor’s advice. The risk of anemia increases after the first trimester.
Comfortable clothing: Wear loose and comfortable cotton clothing from now on. Tight clothing can cause discomfort as your body changes.
Body position or posture: Make a habit of sleeping on your left side. This helps increase blood flow to the uterus and placenta.
Skin care: Itching or stretch marks may appear due to the skin on your stomach being tight. So use moisturizer or coconut oil regularly.
Dental care: Gum problems or bleeding may increase during pregnancy, so brush your teeth regularly and consult a dentist if necessary.

Smoking or going near the smoke of bidi-cigarettes is also very dangerous As soon as you notice Very early signs of pregnancy 1 week, you should make your life completely white and clean so that the baby does not suffer any harm.

Bye go, if you have the habit of going to the gym regularly, then stop lifting heavy weights or doing exercises that put direct pressure on the stomach. It is also not a good idea to take a hot tub or steam bath at this time because excessive heat can harm the fetus. Do not hold your urine or stool in any way because there is a risk of getting a yeast infection, which is a big problem for American expatriates. Always wear loose cotton clothes so that your body can breathe it is better to reduce chemical dyes or heavy makeup at this time because these toxins can mix with the baby’s blood through the skin. If you consider yourself a sacred trust and follow these precautions, you can become the mother of a healthy and beautiful baby which will be the best achievement of your life.

The fight between coffee and sleep

I have said before that you should reduce your coffee intake completely this coffee culture in America can disrupt your sleep, which is harmful to the baby. When the body is working day and night for the baby, you have no alternative to deep sleep Give your body complete rest by avoiding staying up late watching movies or doing office work. Your peace of mind means the good health of your baby so give yourself some time.

Anxiety and fear of the internet

Many times, people get scared after reading nonsense news on the internet remember that every person’s body is different. What happened to one person does not mean that it will happen to you if you get unnecessarily scared, your blood pressure can increase, which can be a life-threatening situation for the baby.
