Levonorgestrel
"I just got my mirena inserted yesterday and so far I feel fine. I am 20, and I have a son. The insertion wasn't very painful, though the cramps afterward were a little uncomfortable (nothing that some ibuprofen can't fix). My husband and I haven't had sex yet so I don't know if it'll affect us yet. Still bleeding a little, but nothing serious. I don't know if this review was helpful, but I'll definitely give an update within the next 6 months."
