birth control
"I used Mirena for 11 months for birth control. I am very sensitive so the insertion was painful (lots of cramping and spotting after).  I would then (for the first 3 months or so) get random, painful cramps. I also instantly gained 5 lbs and 10 lbs over this past year in total.  Apart from the hair thinning (which I am unsure was from the Mirena) I got really bad acne on my chin area and on my back. I was hoping that would change bc aside from that, I got no periods at all and it was very effective in preventing pregnancy. I just got mine out today and taking it out was a cinch.  I'm hoping my body will regulate itself quickly."
