Levonorgestrel
"I hate it. Insertion wasn't bad but the cramps afterwards were. I've had it for a month and I'm on week three of my period. I'm always hungry. I have an extra few lbs now and I have an itchy and flakes scalp which I never had any of these issues before. I'm just sick of it and it was my last resort for birth control. I'm one of those unlucky woman who has a reaction to all of them. It's not good and I wouldn't recommend it to woman who have reactions or bad experiences with birth control. Everyone is different."
