Descrizione:
Thirteen weeks into your pregnancy, or 11 weeks after conception, your baby is beginning to make urine and release it into the amniotic sac, making amniotic fluid. Yes, that's right. Your baby swallows the amniotic fluid and then urinates it back into the amniotic sac, making amniotic fluid.
