Levonorgestrel
"I have had the mirena now for 3 months and the initial insertion was horrible, I didn't know to take ibuprofen, because although I had read up on side effects and the insertion I didn't see about taking anything nor did I think to. I have a relatively tight vagina as well which makes gyn appointments no fun already but I'm not one for taking pills so again I didn't think to. 

That said, the insertion was terrible, so painful I passed out on a the table and the pain continued for hours only to be subsided when I was given an 800mg ibuprofen. I cramp slightly more but bleed a lot less, the only big difference I've seen lately is it is so hard to sleep and Ian anxious all the time. Otherwise so far so good I guess."
