Your Pregnancy: Week 21 that a stretch mark?!! Take deep breaths and remember — they'll fade after delivery. Your skin may also feel dry and itchy, especially over your emerging bump. Take a cue from your fetus, now coated by vernix (a milky, protective cream), and slather on the lotion.

Baby's now the size of a pomegranate!
Baby's digestive system is busy creating meconium (a tarry black substance made of swallowed amniotic fluid, digestive secretion, and dead cells), which will fill the first diaper after birth. And, if baby is a girl, her womb is now stocked up with her lifetime supply of six million eggs (the number will drop to around one million by birth).
