I have recently had my period, 14/03 and my cycle is usually about 25 days and 7 days of bleeding. My hubby and I are trying to fall pregnant (am not on and was never on the pill) and thought my period ended on Sunday 20/03 as all was clear. We then had sex Sunday morning and all was fine. On Monday afternoon I suddenly bled as if I had my period all over again and now I have a brown discharge that does not seem to stop. What could the problem be? Is it anything to go to the doctor about?
