My cervix seems to be swollen. I have very slight, almost unnoticable, cramping and I had my period starting on the 18th of february and ending about the 21st. On the next tuesday me and my boyfriend were going to have sex but as we were "warming up" I started to bleed pretty badly but then it stopped right away. We didn't have sex and haven't had sex since because I went back to college. This has never happened to me before, along with the smollen cervix so I am a little concerned. Any suggestions of what the problem could be?
