"i am on my 2nd mirena. i am 36 yrs old, no kids and never want kids.  the insertion was very painful, but tolerable. i did tear up a little from the pain and i took deep breathes to help get thru it. i love the mirena. i did not gain weight from it, however, i am a runner. no acne, no abdominal pain. i am spotting brown, but that&#039;s normal after insertion..for the 1st couple weeks. i did not get my period the first time around, so i am hoping the same this time. not having a period for 5 years is amazing. this alone is worth the uncomfortable pain during insertion. take 800mg of ibuprofen 1 hour before..it helps a little bit. but you still feel it...feels like the most painful cramping, you can ever imagine. ugh. ps. #never been in labor."
