Can someone please help me? For 2 of the past 3 months my period has been weird. When I say weird I mean that in October my period was lighter than usual which I thought was coming from being on antibiotics for a month. In November my period was normal so I thought everything was fine. Now for December my period is weird again. When I wipe is the only time I see blood. It is more blood this time than I saw in October. I am on Lo-Ovral (birth control) and have been for a while. I have taking several pregnancy test in October and they all came back negative. I also had blood work done at the doctors for other health reasons and they never said I was pregnant so I'm sure I'm not. Does anyone know what the cause of my problem could be?
