21 Weeks Pregnant - Signs of Pregnancy
At 21 weeks pregnant, as your bump grows you may find it more difficult to get comfortable in bed.
Your baby may also be a lot more active at night time and as a result may be keeping you awake with stronger kicks!
Try to rest as much as you can.
Although your baby's digestive system can now absorb some nutrients from the amniotic fluid, most of his nutrients still come from the placenta. His white blood cells are forming and his skin is becoming less translucent. His tongue is now fully formed.
