Levonorgestrel
"My experience with birth control in general is crappy. With depo and nexplanon I bled everyday for six months each, among many other side effects! They ruined my sex drive (so has Skyla). The IUD is my last shot.

I continued to bleed daily with no cramps for the first few months. My period are becoming more normal, but I'm experiencing much worse cramping than my periods before it! The pain has left me unable to work, and it comes and goes like contractions in childbirth do. I have to do breathing exercises to get through it because painkillers like ibuprofen do nothing!

The pain is like when I had it inserted. I was warned I may have "slight" cramping, when I had severe cramping for 17 straight hours! It only stopped when I went to sleep."
