So I had sex for first time yesterday . I was a day shy of being 10w PP. I feel like I've had a baby all over again. Is this normal? I don't know if it's something that happens, if it's cause I was use to my baby's father's baby carrot and was with a diff man much bigger or if this isn't normal and i need to call my doctors office?
