"i was pretty scared to get my mirena in after reading reviews on it, but i have to say personally that i really liked the mirena. i got mine put in two weeks ago and yes the procedure was very painful since i am 18 and never had any kids. i would recommend taking advill extra strength gel caps, those seem to work the best for me. hours after i got mine done i was in a bunch if pain. i had really bad cramps, fever and i was puking which was not fun at all. but the next day all the pain went away and i felt like myself again. i only bled for three days after getting it in then it completely went away and i am in no more pain! i am able to have sex with my bf normally, and the only side effects i endured was loss of appetite."
