I am 25 weeks pegnant with our third baby (a boy) and when my husband and I have sex, I swell afterwards around the opening to my vagina. It's uncomfortable, but no excruciating pain. The swelling goes down fairly quickly, but there is still a little bit of discomfort even after the swelling is gone. Never experienced this with our other two babies, either. I have my regular appointment on Wednesday but I was wondering if anyone else has ever had this happen? The sex is great! It's just afterwards is the problem!
