Had sex this morning and it was more painful than usual. Before when I was on my period he normally wouldn't be able to go very deep without it hurting and the same thing happened today. It's the first time I've had this happen since getting pregnant (I always figured it was because of my cramps). He said he didn't feel like he was hitting anything either. Like an hour or so ago I started noticing some dull sharp pains that come and go just barely inside, possibly pelvic floor? Has anyone else experienced this?
