Levonorgestrel
"I had been on the pill since I was 14yrs old for excruciating period cramps along with extremely heavy bleeding (I could go through a super plus tampon in 20min!) Now, at 23, on May 9th I had the Mirena inserted. The procedure was extremely painful to the point that I felt like I was going to pass out, my hands were clammy, and I had a death grip on the sides on the exam table. (I don't have any kids). To date, I have gained 30 pounds and nothing I have done to lose it has worked. I've lost 40+ pounds twice in my life, so I know how to lose it. I'm also tired ALL the time. I can literally nap at any point in the day. And I have painful ovarian cysts (which I knew was a side effect prior). Seriously considering taking it out."
