I have been on birth control for 13 years. I was given the depo shot for 3 years and now have the Mirena. I have had it for 2 years and have not had a period since I was on the depo shot. Recently I have been having bloody discharge some having blood clots in them. I dont have insurance and have been unable to see a doctor. I am worried sick that something is wrong. Any ideas on what could it be or is it nothing to worry about?
