Pregnancy Calendar - Week 21

Your Baby:
Your baby's facial features are now fully formed and she could even have a head of hair, so this is pretty much what your baby will look like on arrival. Your baby's foetal bone marrow has started making cells and your baby continues to practice swallowing amniotic fluid for when she arrives. Your baby weighs between 290-310 grams and is about 18cm long.

If you're feeling especially frisky, it is common for second trimester hormones to increase your sex drive. Sex during pregnancy is completely safe (unless you have complications, which your doctor would advise). Your breasts may start secreting colostrum (the first milk) in preparation for the baby's arrival, and you may also find your nipples have darkened in colour.
