Okay so this is going to be tmi for some... You were warned.
My partner and I were having sex and with each thrust there was pain in my lower abdominal region. Like where id say my uterus is. Not the cervix... Higher up. Anyway, it was pretty shallow sex at first so I just ignored it thinking it would go away but then a slightly deeper thrust hurt so much I pretty much jumped right away from him. It was like a quick stabbing pain. Like someone has taken a knife and stabbed me in the uterus.
This has never happened before. Sometimes sex might feel a little bit uncomfortable if we're in a weird position or something but we moved around and it didn't change. It can also feel weird sometimes of my uterus is sitting a little lower due to certain times in my cycle but that's just discomfort not pain.
Any idea what could have caused it? It ached mildly for maybe 15 mins afterwards as well.
