birth control
"I love this! I'm 19 and never had sex or been pregnant. The insertion was honestly just about as painful as an ovarian cyst I had burst less than a year ago. IUD insertion pain lasted for about 2 minutes, and after they took out the long metal tools used to pry open the cervix, I felt kind of nauseous and like I had major period cramps. I laid down for about 5 minutes afterward. Now, three weeks later, my discharge is a bit more than normal and there is blood streaking it, just the lightest tint though. But I absolutely LOVE this birth control. 
My mom had hers in for about 5 years but got pregnant after it slipped down, the fetus conceived above the IUD. The baby had a .04% chance of living after removal, and today she is six years old."
