I done had a D&C (12/18/14) done and it still do the same. I was on birth control for almost 6 months yes I was having a normal period, but I just didnt want to be on BC. I stop talking them 3months later I started spotting thinking my period about to start. Will the next day it went off 6days later it start back went off 2 days later it came back on the next day it went off 2 days later it came back on and went off the next day it did that about 2weeks. At the end of the 2weeks it came on and don’t want to go off. Its not bleeding heavy just like spotting enough to see in the tissue when you whip. Just say if I wear a pad I can were it all day. I’m at my withend just don’t know what to but pray. Could you please help me and tell me what I should do or tell the doctor what to do? Is there a test he can run?
