Back to Pregnancy Week by Week Guide

I am sure that you would have taken your home pregnancy test by the 2nd week of your pregnancy. If you are still unsure about your pregnancy, the 3rd week is the best time to fix an appointment with the doctor to confirm pregnancy.

Changes in Your Body at Week 3 Pregnancy

You might experience spotting in this week. This is called implantation spotting. This happens when the fertilized egg burrows itself in the uterine lining.

At 3 weeks of pregnancy there might be a little loss in weight due to nausea and also a loss in appetite because of the hormonal changes in your body. Don’t worry about it too much and continue with a well balanced nutritious diet into the 4th week of your pregnancy. Together with this, some other symptoms that you might notice in the 3rd week are:

  • Nausea
  • Heightened sense of smell
  • Food aversion
  • Frequent urination

Internally this is what happens to your body: The part of the foetus that will grow to become the placenta now begins to produce the hormone HCG (human chorionic gonadotropin). This hormone helps your ovaries to stop further release of any more eggs.

Your Baby’s Development at Week 3 Pregnancy

Your baby is now just a tiny ball with hundreds of cells that are multiplying at a very fast pace. This will be an exciting week for you because this is the first time that you will get a chance to see your baby growing inside you.

In the third week, the foetus begins to develop its:

  • Eyes
  • Hair
  • Brain
  • Head
  • Spinal cord
  • Gastrointestinal tract

Its skin colour also gets determined at this stage. Also the amniotic fluid, that will cushion your baby in the weeks to come, begins to form..

At 3 weeks of pregnancy the foetus is only 2 – 5 mm in size but has a heart that is beating. Read more about what you can expect during this period in our free e-book  ‘A short Guide to Managing Pregnancy

Week 3 Pregnancy Tips and Advice

Once your pregnancy is confirmed, choose an OB/GYN whom you are comfortable with for you will be in touch with her over the next few months.

At 3 weeks of pregnancy make a list of questions before visiting your gynecologist. This should include questions like how often would you need to visit, changes in your diet and lifestyle and vitamins that you need to have now.

There is no need for you to quit your job. Continue with your normal activities, albeit a little carefully.

Week 3 Fun

Make a scrap book of your pregnancy weeks. It could have pictures of your growing belly, ultrasound reports or even a bill of the celebratory lunch or dinner that you had with your husband once your pregnancy was confirmed.

Put your feet up and get yourself some rest. Curl in with your favourite book or watch your favourite movie.
