Bleeding between periods after LEEP

SO i had a LEEP back in april. I had to take my birthcontrol for a month straight so not to get my period right after the LEEP. That period was pretty much normal. Then the next period was pretty heavy and more painful then my usual periods are. But they lasted the same amount of time as usual. So abou 6 days after my period ended I got a bladder infection, was put on an anti bacterial. The next day i started bleeding for no reason. It wasnt bad just a normal mild flow, little pain. Its lasted for 4 days and is now gone. Im just wondering if this has happend to anyone else or if you might know what it is. I havent been able to get into my doc as of yet and im kinda worried. thanks.
