Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long, the length of a carrot. You may soon feel like she's practicing martial arts as her initial fluttering movements turn into full-fledged kicks and nudges. You may also discover a pattern to her activity as you get to know her better. In other developments, your baby's eyebrows and lids are present now, and if you're having a girl, her vagina has begun to form as well. 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).
