birth control
"Had it for years and love it. Changed it out after not having a period for years and boy it was painful. My first Mirena was nearly painless - just a little tuck. This time it stabbed me hard a few times (quite painful)  but each time it was over in seconds. I had menstrual cramps for an hour and that was it. I didn't even get my bleeding back (just a little right afterwards). Yeah! May advice:
 if you choose the Mirena be patient - the first year I constantly bleed off and on but then my period disappeared. Find a doctor who has done this a lot - I believe experience is the key! Also - have it done when your cervix is dilated during your period. I took Misoprostol for that the night before but that did not help."
