Pain while having intercourse

Leah • I'm a mother of 4 boys and this is my 5th baby!! Can't wait to find out what my new addition is!!
This is my fifth baby but I've never experienced pain during sex ever I mean it hurts so bad I have to stop and I feel so much pressure n pain in my rectum at the same time! I'm having regular bowel movement so it's not constipation, but not sure what else it could be ! Read something bout it being normal and then maybe could mean ectopic pregnancy???!! Please help!!
