I hadn't had sex for 9 months. I recently entered a relationship. At first I had a little pain during intercourse. I put this down to not having sex for a while. Know, though the pain has gone, i have now started bleeding (light), and have no idea why. It's definately not my period, and it settles down within a day.. . I'm not sure if it's a cause to worry. Could this be the result of not having sex for a while??
