Levonorgestrel
"I recently had the paragard IUD and I got it inserted at the age of 16. I'm currently 18 and had it taken out a week ago and got the Skyla inserted and I'm 18 now. The paragard was terrible for me because the copper wasn't good for my uterus and my uterus was pushing the paragard out. I was having bad cramps on and off my periods with the paragard too. When I got the Skyla, I had brief spotted and cramps for 1 day. Also, I never had a child either but I'm in college, and in a relationship with my boyfriend for 2 years now so I though that was the best option for me. So far I having good positive affects and hope it continues."
