Levonorgestrel
"I've had Skyla for about 5 months and have mixed feelings about it. The insertion wasn't that big of a deal (uncomfortable but tolerable) but it's the side effects I've been having issues with. First of all, I bled everyday for the first two months along with horrible cramps. It's gotten better since but I still spot a lot. I'm a person who has always had strong reactions to hormonal bc and I am starting to notice mood swings and an overall more sad mood than normal. I don't know if this is bc of Skyla but it probably is because it's not like me to feel like this. I also have lost about 15 pounds and know I have an ovarian cyst which I never had before. I'm considering getting it out even though it's nice to not take a daily pill."
