As far as I know, HPV does NOT cause any discharge. The only symptom I know if is possibly warts, but not always. There could be no symptoms. Your cervix could be hurting from having intercourse if intercourse has been painful. Intercourse should not be painful though. Have you asked your doctor why this is happening? HPV does not prevent you from having children. I've been told that you CAN have children even if you have HPV. I had a LEEP procedure done, which has tiny, tiny risks for problems with pregnancy, like 1-2%. I don't think you should be worried as long as you're seeing a doctor and you find out what's wrong.
