Week 21

 

 

This is a big week for both you and your baby as your baby really starts showing and it settles into its final position.

 

 

Pregnancy MomWhat Is Happening To Your Body

You should have gained about 10 to 15 pounds by this point in your pregnancy. Talk to your doctor if you’ve gained significantly more or less. As long as you maintain a healthy diet and stay well hydrated, you should be right on track. Also, moderate exercise is a great way to stay in shape during your pregnancy, get strong for birth and minimize pregnancy symptoms like excessive weight gain, backache and varicose veins. If you haven’t been exercising yet, talk to your doctor before starting, and remember to go slowly and pace yourself.

 

Your ankles and feet may begin swelling by the end of the day. Make sure to drink water and get plenty of rest to combat swelling. In addition, try to schedule 30 minutes or more of relaxation time in the evening where you can raise your feet to reduce swelling.

 

Don’t be afraid if your belly button pops out — this is normal in pregnancy. It’s probably a good time to invest in some comfortable maternity clothes, if you haven’t already.

 

Pregnancy BabyWhat Is Happening To Your Baby

From this week on, your baby will likely be measured from head to heel instead of crown to rump. Your baby should measure around 10.5 inches (26.7 cm) long from head to heel, or roughly the length of a carrot. At this point, your baby weighs around 10.5 ounces (297.7 grams).


Your baby’s digestive system has developed enough to start absorbing water and small amounts of sugar from the amniotic fluid that it swallows. Most of the baby’s nourishment, however, still comes through the placenta.


Your baby’s bone marrow has also developed enough to contribute to blood cell formation. Your baby’s liver and spleen have been responsible for creating blood cells until now. The liver will stop producing blood cells a few weeks before birth, while the spleen stops producing blood cells around week 30.


Your baby is also developing visible eyebrows, eyelashes and hair on his or her scalp.
