Levonorgestrel
"I have been on DepoProvra for about 10 years on and off. Too long according to my new OBGYN, and he suggested Mirena since I am not ready to cut the ties just in case I decide to have children in the future lol. I have a 13 and 10 year old lol.... But after insertion I had cramping and mild bleeding for 2 days. I have not had any bleeding since then. It has been almost a month! The side effects I am experiencing are breast tenderness, and increased libido. The shot killed that lol. I love it so far and I am very happy."
