Skyla
"I had Skyla inserted June 8, 2016. The insertion was more uncomfortable than painful, and I have a very low pain tolerance. I had it inserted while I was on my period. DO NOT work after the insertion. I thought I would be fine, but I felt like I was going to pass out and had extreme cramps. For the first couple of months I had cramps and bleeding every single day. I still have random intense cramping followed by spotting, but skyla is worth it. You don't have to worry about taking a pill and my periods are finally starting to regulate after years of randomly getting it and never knowing when it was coming. Def recommend, just have to deal with side effects for the first couple of months."
