OK so I know can be a number of things but 3 days before my period it started out with old blood I had my period for a week and 1 day. Ever since my period stopped I've had to wear pads because of what looks like old blood been going for 5 days now past my period. I didn't have cramps or anything during my cycle, was not normal at all. Have had bloating and just a little but of what feels like tightening in the lower abdomen. Can you give me any clues or info of what might be wrong??..
