The placenta has taken over production of the hormones needed to sustain your pregnancy. Your baby is also making some of its own insulin and bile. Your baby even urinates into the amniotic fluid in small amounts every 45 minutes or so.
Your baby’s heart pumps about 25 quarts of blood a day. This will increase to be about 300 quarts by the end of your pregnancy. All of the teeth have formed and you even have a scalp hair pattern!
Your baby is about 3 ounces (85 grams) and 6.3 inches (16 cms). The gender may be detectable by ultrasound. Though gender predictions at this point are much harder to rely on.
