Skyla
"I've had skyla for 4 months and decided it's not for me. The insertion was the most painful experience of my life. The painful cramps I got with insertion pretty much lasted for a week. The second week of cramps weren't as bad but they were still awful, only 800mg Ibuprofen helped. It caused my periods to stop, tired all the time, some mood swings, acne and cramps. Worst part we're the cramps/the cystic acne, as time went by these worsened. Removal was quick and practically painless other than a short cramp."
