birth control
"Ladies!!!  Do yourself a favor and stop reading these.  Everybody is different and we all have different insertion experiences. 

I just got mirena inserted this morning. I am 24 years old and I've never had a baby. I was extremely nervous, as this was my second attempt at inserting mirena. I went last week and my cervix was too tight so they sent me home with a prescription that was to be put in my vagina the next week before I go in again. The second time (this morning) was a lot easier. Yes, it does hurt a bit but nothing I couldn't handle. Honestly the worst part for me was the cramps afterwards. I had bad cramps for about 5 minutes and ended up throwing up. After that I felt much better."
