Hello! I wanted to ask something, although it's embarrassing but I'm asking ? I apologize Pregnancy is 17 weeks and today with my husband we were having intercourse and after I lay on my back and here I feel a weak movement and something hard is standing there, then the left side goes away then to the right or up and I am pregnant for the first time and I wanted to ask is this normal? Did we damage the baby?
