3 Weeks Pregnant: What to Expect

Your baby is developing fast and it is only fair that you should know everything about it. Find out about the exciting foetal development in the 3rd week of pregnancy and other pregnancy milestones that you achieve during this week through this article.

Your Baby’s Growth During Pregnancy – Week 3

It’s the 3rd week of your pregnancy and the good news is that the fetus is already under development. During this week your baby is just a tiny ball with 100’s of cells that are multiplying rapidly. The part of the tiny ball or blastocyst that will develop into a placenta starts producing pregnancy hormone (HCG) in the 3rd week of pregnancy. This hormone stops the further production of eggs and triggers an increase in the production of estrogen and progesterone. These hormones ensure that your ovary doesn’t shed the uterine lining. Your little blastocyst is safe and sound in your uterine lining during the 3rd week and receives oxygen and nutrients through the tunnels that connect the little ball of cells to the blood vessels in the uterine wall.

What is the Baby’s Size?

This week is crucial because, during this week, the fertilized egg safely implants itself in the uterine lining and starts developing with the help of oxygen and nutrients that it receives through the blood vessels of the uterine lining. While the development itself is interesting but the 3 weeks pregnant baby size is negligible. In technical terms, baby’s length is 0.0in and baby’s weight is 0.0gm.

Common Body Changes

From the onset of pregnancy till the end, body changes during pregnancy in women are drastic. In the first few weeks of pregnancy, the difference that a woman feels in her body and demeanor are quite similar. In fact, each of these symptoms or changes heighten with each passing week of pregnancy. Some of the continued body changes in the 3rd week of pregnancy are soreness of breasts, elevated basal body temperature, exhaustion, and loss of appetite.

Symptoms of Pregnancy at Week 3

Symptoms of pregnancy differ from woman to woman but here are a few common symptoms that may help you to find out a week before the pregnancy test that you are pregnant.

  • Swollen or tender breasts
  • An elevated sense of smell
  • Always exhausted
  • Frequent urination
  • Dislike towards selective food
  • A lurking sense of vomiting and nausea
  • Bleeding or to be more accurate spotting, while the egg implants itself in the uterine lining
  • An all-time elevated basal body temperature

Belly at Week 3 of Pregnancy

You will be excited to see minor body changes taking place during the 3rd week of pregnancy. But a growing belly is not one of them. You may feel bloated but that’s not really because of the growing baby inside. You have quite a few weeks ahead of you till you actually start looking pregnant. So, you can safely preserve your secret till you are ready to tell the world that you are expecting.

3 Weeks Ultrasound

At three weeks, your baby is a very tiny fertilized egg called the marula and is as small as a grain of salt. It is also on the move and hence very difficult to be detected during the ultrasound. By 4th week though you may be able to see a thicker uterine lining confirming that the little marula has reached its destination and is safe and secure in the uterus for the next nine months.

What to Eat

Before you start eating for 2 people, stop and listen to what the doctors have to say. According to the doctors, a mother to be is only supposed to gain 1 to 2 kg in the whole of the 1st trimester. So, pull back and don’t indulge in excessive eating. Just continue to eat a healthy and wholesome meal with a daily intake of prenatal vitamins including folic acid. Here are a few diet tips for you for 3rd-week pregnancy food.

  • Folic acid is a vital vitamin for the proper growth of the fetus. So sooner you start its intake, the better. Whole grain and leafy vegetables are rich in folic acid or folate. So, be sure to include them in plenty in your daily diet. And for extra insurance, please don’t hesitate to take a supplement for folic acid.
  • Avoid junk food as much as possible. Cut down the intake of extra sugar and white flour in any form. Throw saturated fats out of your diet and replace it with salads and grilled meat instead of deep crispy fry food. Junk food, especially fats increase the risk of pregnancy nausea and vomiting. So better say no to all kinds of junk.
  • Your pregnancy diet for the 3rd week should include lots of leafy vegetables, fruits like apricots, carrots, mangoes etc, hearty whole grains and low-fat dairy products. Eat and stay healthy for the sake of the little angel growing inside you.
  • Skipping your meals and hurrying through them is a big ‘no’. Relish your meals and start eating a wholesome meal three times a day. This habit will take you a long way and ensure a steady supply of nutrients to your baby, throughout the pregnancy and even later.
  • Scan your dietary habits and get help in case you have an eating disorder. It is important that you enlist help with a dietician before it’s too late.
