So I just got off birth control due to mental health issues being made worse by it. And we had unprotected sex where he came in me on the last day of my period then I took the first pill of a new pack but and then didnt take anymore after it and I'm now about a week from my estimated due period and it feels like my uterus is hard like it was with my first pregnancy except way earlier than last time.. has anyone had this happen and been pregnant??
