birth control
"I had an ectopic pregnancy after only 7 months of using Skyla.  My right fallopian tube was removed, I was in the hospital for 5 days and was in the worst pain of my life.  When I got it it sounded great - no worries for three years, more cost effective in the long run, but as it turned out I shelled out almost 300 dollars for 6 months and then had to pay thousands in hospital bills on top of that.  I wish I had opted for ANY. OTHER. METHOD."
