Read this post to get answers to all your questions on the First Trimester of pregnancy.


As you are reading this, you may not look pregnant yet, but chances are you’re already feeling it. That’s because a flood of pregnancy hormones is prepping your body to host the baby for the next nine months. There would be some aches and pains and slight discomfort( even more sometimes) but believe me when I say it is going to be worth the incredible process that is happening inside you: You’re nurturing a life! This is your superpower :)


Since all of us have different menstruation cycles, you may not realise that you are pregnant when you miss your cycle for the first time. In fact, many women don’t realize that they are pregnant even in the 4th week of pregnancy and it is perfectly normal.


First Trimester of Pregnancy


How long is the First Trimester of Pregnancy?

Baby bump with a woman's hand and the Test says " All you need to know about the first trimester of Pregnancy

The first trimester lasts from Week 1 to Week 13 of the pregnancy. The first week is considered to be only a technical pregnancy and not the official one because, in the first week, the doctor calculates the first day of your last monthly menstrual cycle (also called LMP) and it is from this day that your nine month or 40 weeks pregnancy term is calculated.


Calculation of LMP gives an idea about the expected delivery date.




Very Early Signs of Pregnancy?


The body changes during pregnancy may vary in each individual but there are a few common changes that you may experience in the first few weeks of pregnancy which are a good indicator that a new member may be added to your family soon.


Here is a list of symptoms that might give a signal to go ahead and take a pregnancy kit test:

  1. Missed Period: The most obvious pregnancy sign is a missed period, but a missed period doesn’t always mean a baby is on the way. Stress, diet, or an irregular schedule can also be the cause of this false alarm. So it’s best to wait for at least a week after a missed period before you take your pregnancy test.

  2. Cramps and Tender Breasts: You might feel cramps in the lower abdomen and your breasts will feel tender and hurt when pressed. This happens because the body prepares the breasts to produce milk in later stages. However, you might not notice the tenderness if you have been on birth control pills.

  3. Darkening of areolas: For many women, hormones can cause the areolas, the circles around nipples, to widen and darken during pregnancy. This occurs as the body prepares itself for breastfeeding.

  4. Spotting: About five to ten days after conception, some women may notice light spotting when the embryo implants in the uterus. This happens when the uterus shed its lining through the vagina to facilitate the implantation of the embryo. This may be mistaken as a light period by some ladies. Hence, if you think you’ve had a very light period this month, you might want to confirm.

  5. Increased urination or constipation: When you’re pregnant, your uterus presses directly on the bladder leading to more frequent urination. This added pressure and changes may also cause constipation. As the pregnancy progresses and the baby grows, the uterus expands and presses against the bladder and other organs. However, that happens in the later stages.

  6. Nausea or Morning Sickness: About 80% of women feel nausea in the morning during the first trimester of their pregnancy. This happens due to a sudden surge in hormones. While for many women morning sickness isn’t confined to the morning they may feel it all day long, some women may tend to feel nausea in the late evenings.

  7. Fatigue: Feeling very tired is one of the first and most common signs of being pregnant. It takes a lot of energy to create a baby and the frequent throw-ups, inability to eat properly and lack of energy adds up to this fatigue. If you are pregnant, expect this tiredness to lessen by the 12th week when the placenta is fully formed.

  8. Sensitivity for smell: Many women have an increased sense of smell during pregnancy. This symptom is one of the most common early signs that you could be pregnant. For some, the smell of some peculiar dishes like Dal or non-veg may cause nausea. However, smell sensitivity may vary from woman to woman.

  9. Unusual hunger or cravings: Your pregnant body is working hard to grow an environment safe for your baby inside you. It requires close to 300 extra calories every day. Your body needs a constant supply of energy due to which you might feel hungry all the time. Some women find themselves craving food that they would never normally dream of eating while some may not experience anything of this sort.

  10. Headaches and lower back pain: The frequency of migraine and headaches can increase with pregnancy. Lower back pain is a very common symptom in pregnancy which can alleviate the passage of trimesters. This usually occurs due to the pressure being built up on the lumbar areas.

  11. Mood swings: With the upsurge in hormones, it is common to experience irritability during pregnancy. Emotional mood swings are caused due to the adjustment of the body according to the varying levels of hormones in the body.

  12. Feeling dizzy or fainting: Shifting hormones, combined with the need of the heart to pump more blood through the body can cause blood pressure to gradually decrease early in pregnancy. As a result, many women experience episodes of dizziness or feeling lightheaded. Lack of nourishment may also be a cause of fainting or dizziness.

Baby Development in the First Trimester (Week 1 to week 13 of Pregnancy)


While you now know what is happening to your body when you get pregnant, I am sure you want to know what happens to the little life inside you. Here’s a week wise brief about how your little baby grows inside you during the first trimester-


Week 1- You may not be officially pregnant in the first week. Your body actually prepares for the actual conception during this week. The uterus is thickening so it can house and feed your fertilized egg once it implants.

Week 2- If sperm can make its way to the egg waiting in your fallopian tube, conception takes place. A few days later, you could notice some light spotting. It might look like your period, but it’s actually a sign that the fertilized egg has attached itself to the wall of your uterus.

Week 3- Finally, you’re pregnant! Sperm and egg have officially merged into one single cell, called a zygote. Inside that cell, a lot of genetic activity takes place to decide the baby’s gender, hair, personality etc.

Week 4- A sonography may be done to confirm the pregnancy and your baby may be big enough to be visible on ultrasound now, but just barely. The embryo is smaller than a grain of rice.

Week 5- This week your baby’s tiny face starts to form. The nose and eyes begin to take shape.

Week 6- You can now listen to your baby’s heartbeats during sonography. The lungs and digestive system are also starting to branch out, forming the organs that will help your baby breathe and eat in just a few months.

Week 7- Your baby is almost the size of a grape. Even though you’re only in your second month, your baby’s body is already forming every organ it will need including the heart, kidneys, liver, lungs, and intestines.

Week 8- Here comes a growth spurt and your little one will double in size this week.

Week 9- You can now compare your baby to a strawberry. Baby’s head is still huge compared to the body, but it will get more proportional in the weeks to come.

Week 10- Your uterus is the size of a large orange now, and your baby is around 3cm long. Your baby now has a real profile with well-defined eyes, mouth, and ears. The neural connections in the brain start to develop rapidly.

Week 11- The first trimester is now approaching its end and your bump may start to show soon. The baby’s head and body will now become proportionate.

Week 12- Everything is now in place – the organs, limbs, bones and muscles are in place and growing. By now the baby looks like a fully formed person with more organs developing like fingers with nails, and a kidney ready to produce urine.

If you are working check your organization's maternity leave policy. Most organizations expect their employees to declare their plans for maternity leave by week 12 of their pregnancy.

Week 13- Hopefully you’re over any morning sickness you had. Now, you should be putting on weight. Baby bump will now be quite evident.


What to Eat in your First Trimester of Pregnancy?


Eating healthy should be a lifestyle especially more so during pregnancy. During pregnancy, the mother-to-be needs to consume extra protein and calcium for the needs of the growing baby. They say to eat for two when you are pregnant. Rightly so, but keep in mind the size of the 2nd human :)


Ensure that your food includes a lot of dairy products, legumes, sweet potatoes, salmon, eggs, broccoli and dark leafy vegetables, lean meat, fish liver oil, berries, whole grains, avocado and lots and lots of water.


Watch out for any foods you are allergic to. Load your meals up with food that will supply folate, zinc, calcium, iron, and fibre to your body. If you are unable to get these five critical nutrients from the food, you eat then don’t forget to consult your doctor for supplements.


Do’s and Don’ts in the Initial stages of Pregnancy


The initial weeks of pregnancy are a time of joy and anticipation both. You should keep a few things in mind:

Do’s:

  1. The moment you realize that you are pregnant or if you observe any of the symptoms mentioned above, consult an Ob-Gynae to understand all the basic tests you might need to undergo. These tests are conducted for both partners and rule out any complications related to genetic diseases.

  2. Start the intake of prenatal vitamin supplements as advised by your doctor.

  3. Follow your doctor’s advice and bring any suggested lifestyle changes or dietary habits.

Don’ts:

  1. Don’t take any over-the-counter medicine. Consult your doctor before continuing any previous medication.

  2. Drinking alcohol, smoking or having any other drugs is an absolute no for a healthy pregnancy.

What to Shop For in the First trimester?


This is the most exciting part of any pregnancy. In the first trimester, there isn’t really too much to shop for however, you may like to consider buying the following:

  1. Some good books on pregnancy.

  2. Comfortable cotton bras.

  3. Good moisturizer for your skin.

  4. Body pillows to soothe back and neck pain

  5. Subscription of some good Garbhsanskar music or any meditative music to calm your mind.
