Skyla
"I got the Skyla inserted three weeks before I got married (virgin until then). Putting in Skyla was fast, but easily the most painful experience of my entire life. It sounds like someone is shooting a rubber-band gun and it feels like someone has shot your uterus. The cramps were the worst cramps I have had in my entire life- I couldn't focus, I was in tears- really the most painful experience ever. The cramping pain and bleeding didn't stop for about two months and periods are still extremely painful. I have bad mood swings, I get depressed all the time, and my libido is definitely decreased. My husband can also feel the wires sometimes and it's painful to him. I'm not pregnant, so it works... but I'm not sure it's worth the side effects."
