"i am 21 years old and i got my mirena inserted july 2nd because my gyno recommended it to me instead of pill birth control. i didn&#039;t take any medicine since i didn&#039;t have any on me but i did experience a terrible cramp feeling when i had it inserted. i took advil for the next 48 hours. i still experience cramps every day but it&#039;s not unbearable. i am hoping it goes away soon. my period is gone but i have been spotting a tiny bit, nothing crazy. after hearing all these crazy stories i am getting a little nervous about this. i will right again in a week or so."
