birth control
"I love this! I found the insertion virtually painless, and only had a little bruise for a couple of days afterwards. I have a short (1-2 days) and very light period once every 12-13 weeks which is a little irritating, but much better than it was! The only other thing I have noticed is I get headaches from time to time, which I never did before. This is the only reason I have marked it down. Definitely worth a try, and if you don't like it you can have it removed."
