Levonorgestrel
"I just had Skyla placed today & it wasn't NEARLY as bad as I thought it would be. I am 24 years old, never been pregnant. Skyla seemed like the right option for me because I'm a busy student & it doesn't require remembering to take a pill every 24hrs. The whole procedure took maybe 5 minutes & was very similar to getting a pap-smear.  It was way less pain then my periods are. I usually have moderate cramping with periods, but this was just slight cramping in my lower abdomen & only lasted for about 1 1/2 minutes of the procedure. It was quick & easy. I did take 3 pills of ibuprofen an hr before going to my appointment so that probably helped a bit. It's been about 6hrs & I haven't had any spotting yet or cramping. Would definatly recommend!"
