For the past two years I have had extremely painful periods characterized with little bleeding, extreme dryness, really only passing black, rubbery clots (which I have to pluck out, they don t fall out on their own due to the dryness). I am at a loss what to do. I feel like i am being stabbed with a super hot metal rod, it hurts so bad. I am 20, 5 7 and 180 pounds.I have been on birth control for 6 years
