 2nd week of pregnancy

While there’s not too much going on visibly in the first week of pregnancy, if you’ve been going crazy with anticipation, the second week will bring with it a flurry of all kinds of activities. Although you may not notice many physical changes because your baby is still an embryo, your body will respond to the internal changes in a number of ways. Here’s all you need to know to help you stay prepared.

2nd Week of Pregnancy - What are the signs?
As mentioned earlier, at this stage your baby is still an embryo. It’s made up of about 150 cells that will divide themselves into three layers to later form a foetus. These three layers are:

Endoderm or Endoblast: This is the first layer or the innermost layer which will upon further cell division become the digestive system, the respiratory tract, the pancreas, thyroid, liver and thymus. 

Mesoderm: Also called as the middle layer, this will build the bones, cartilage, circulatory system, inner lining of the skin, muscles, excretory system and genitalia.

Ectoderm or Ectoblast: This is the outermost layer. The ectoblast will go on to form the nervous system, the brain and the skin, nails and hair of the baby.

This is also the stage where the chromosomes begin to combine. The egg (from the mother) always contains an XX chromosome whereas the sperm (from the father) contains an XY chromosome. If the X chromosome from the mom combines with the X chromosome from the dad, the baby will be a girl, but if the X chromosome from the mom combines with a Y chromosome from the dad, then you’re going to have a baby boy. However, you won’t be able to find this out until the foetus is formed, nor should you try to find out since sex determination is illegal in India.
If you’re wondering how big the embryo is at this stage, it’s as big as 0.1-0.2 mm long.

2nd Week of Pregnancy - What should I be doing?
As your body is preparing itself to make room for your baby, make sure the stay of this new little guest is as comfortable and healthy as possible. This means, it’s time to throw all the vices and unhealthy lifestyle choices out of the window.

Quit smoking, drinking, drugs and junk foods, if you haven’t already done so. In fact, make sure even the dad’s off these things. It’s important to have a healthy and wholesome household during this time.

Make sure you get at least 7 to 8 hours of sleep every day. Establish a standard sleep schedule – go to bed at the same time every night and wake up at the same time every morning. Try to catch up on as much sleep as you can during these months, because you’re not going to get much of it once the baby arrives! 

Include Folic Acid and prenatal vitamin supplements into your daily diet and medicine regimen, only after consulting with your doctor, of course. 

If you have been exercising regularly, by all means keep going. But if you aren’t getting much physical movement or lead a heavily sedentary lifestyle, include simple exercises such as brisk walking and swimming into your daily routine. 

Remember, the healthier you are, the healthier your baby will be. Keep your well-being on top priority in the coming months. Good luck!
