birth control
"I have had my mirena since Tuesday (4 days).  I have never had kids.  I was not on my cycle.  I have horrible periods so my doctor recommended this. In my mind I was thinking this is going to be horrible as I had other exams that had me in horrendous pain.  Insertion took about 2 minutes. Only pain I felt was when he was measuring the uterus.  Felt like cramps.  I  did not even feel it going in.  The Dr said ok that's it. I had no idea it was over.  Afterwards I went to lunch.  Little cramps after I got home,  through the night and the next day.  Just took tylenol.  Only spotted the day that I got it.  So far so good."
