Levonorgestrel
"I had the Mirena inserted 3 weeks ago to treat horrible periods which caused anemia. Insertion was no big deal (I've had 5 c-sections). I spotted a few days after insertion then pretty heavy bleeding for about a week. I've had zero bleeding now for about 5 days and had the best orgasm in my life yesterday. Oh, and I am 52 and still able to get pregnant (no menopause yet). So glad I didn't let the scary stories stop me from getting it. I feel like I got my life back. I hope it stays like this."
