I have had my period every day for the last 444 days. It’s starting to worry me and doctors won’t do anything. I am a 16 year old female. Prior to the 444 days of having a period with no break I had extremely heavy periods with cramps that would make me pass out for hours. I do have the nexplanon birth control but irregular periods started happening before. I don’t want to take it out cause it’s helped ease my bleeding a bit more and made the cramps bearable. The blood when bleeding is also black and a consistency of wet chalk. Does anyone know what could be wrong?
