Levonorgestrel
"I just had my Mirena inserted today, I wanted to get a positive review about the insertion out there. I'm 21 & have been on Loestrin Fe for the past 5 months, & Sprintec for a year & a half before that. I have never had children or been pregnant. They prescribed me Misoprostal to take the night before to open up my cervix & I took 800mg Ibuprofen half an hour before the appointment. First she measured my cervix & then inserted the Mirena. Both felt like bad period cramps, more uncomfortable than painful. I've had mild cramps throughout the day, nothing Ibuprofen can't fix. I have no idea if it will work or how my body will take it, but the insertion went smoothly."
