I have been bleeding for a month straight i have a contraceptive coil but ive recently had it checked and it seems to be in place as it should be, i have spoken to the GP and they cant seem to think of a reason for my prolonged periods which have left me bleeding for 20+ days, i am only 19 therefore i am not eligable for a smear test. i also have constant lower back pain cramps and bloating, and was wondering if anyone had any advice?
