Skyla
"I had had my Skyla IUD in for over a year and just recently had it removed because it just did not work for me. Insertion was pretty uncomfortable but like previously mentioned in another post, it was doable (I'm sure contractions will be a lot worse than that was haha).  Like I said, I had it for over a year and I had a period every month, most of which my period lasted 2 weeks! Cramping was worse for me while on the Skyla than on any other birth control. After removal, I've been bleeding pretty steady the last few days and cramping which is supposedly normal. I loved the convenience of not having to remember the pill but I don't think I'll be getting another one anytime soon."
