Hi bonita,

the cervix is more fragile than we think. It is to be expected that the cervix will bleed a little after rough sex. Don't worry, it will stop. If the bleeding is heavy like a period and goes on for more than a couple of days, i'd be going to the hospital or doctor to be checked. Cervical bleeding is even more common during pregnancy (after sex). The cervical lining gets quite thin during pregnancy, and will start to bleed a little sometimes after intercourse. The lining of your nose also thins during pregnancy, so just a simple sneeze can cause a little nasal bleeding.

Good luck
