Levonorgestrel
"I'm writing my experience due to the fact when I was researching skyla I couldn't find very many reviews....my experience wasn't horrible yet wasn't the best I decided to get skyla in Oct of 2014 it was newly out I decided on it rather then mirena since skyla was lower dosed and smaller I haven't had any kids initially the insertion did hurt but wouldn't say excruciating Dr wrote for a valium before hand so that helped I'm sure after insertion felt fine went to work didn't have any crazy cramps or bleeding all was good up until about 4 months in I started getting crazy cystic acne on my face and back never had acne before and started getting really bad sharp pains here and there so I waited skyla out for about 7 months then had it removed"
