"I am 29 years old with no children, I have not been on any type of birth control for the past 3 years. My boyfriend wanted me to get on some sort of birth control.  I choose the ParaGard for that fact that it has no hormones and it last for 10 years. I just had it put in 3 days ago. It was hands down the worse pain I have ever felt in my life.  She had to clamp my uterus with a pair of forceps to keep it from moving away from her. The procedure took about 5- 10 minutes total.  After it was finished I sat up and immediately felt dizzy and lightheaded. I had to lay down for 10 minutes.  I then drove home and played in agony for about 3 hours.  After that it was bearable pain and cramping."
