"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&#039;t like it you can have it removed."
