I'm 21 with no children. I had a really hard time remembering to take the pill and suffered from extremely heavy periods. I decided Mirena was my golden ticket when i found out that it can lessen and even end your periods for 5 years. Although insertion was horribly painful for hours after, i haven't experienced much cramping or discomfort. My problem is the bleeding. It was like a normal period for the first week (by normal i mean light for me) which was great but now i am nearing the 3rd week after insertion and i still have bleeding. i was never one to "spot" so im wondering if that what is happening but either way when will it end?? can the ladies out there who had heavy periods got mirena help me out? the other side effects are not my concern just the bleeding.
