N.M.
I was going to respond raving about the Mirena IUD but I see someone has already done that. But just so it isn't a random opion...I LOVE IT TOO. I have had mine in for 4 years now and I have nothing to complain about. I have tried several forms of birth control (but not the ring) and never had any luck because my hormones get pretty whacked out. I have NO strange symptoms. And I too, was VERY heavy for 7 days every month. And now, I am never sure when that time of the month is..yay! Anyhow, I highly recommend the Mirena IUD. If you have other questions, please feel free to email me, ____@____.com. However, a lot of mommy mags have full page adds on it.
Good luck with whatever you decide to do!!!
