While you did not ask for opinions regarding the Mirena IUD, I thought I'd chime in on that, too. I had a Mirena inserted after I had recovered from the birth of my third child. Except I started bleeding after the insertion. And I kept bleeding. I bled for two months straight, and my Gyn put me on low-level birth control pills in an effort to control the bleeding. But that did not work, and after 4-1/2 months I was still bleeding constantly. I finally had it removed because I just couldn't take it anymore.
And I guess looking back on my posts here, perhaps I am just a bleeder! Like I said, I did have heavy periods even when I was a teen, and I had almost overwhelming bleeding after the delivery of my children (which at the time I thought was normal, too, but looking back on it, perhaps was not). Birth control pills were the only thing that kept the bleeding in check, but after our family was complete I was unwilling to endure the other side-effects of hormonal birth control.
Anyway, if you would like to avoid surgery, then an IUD might be worth a try. But like anything else, they don't work out for everyone in terms of slowing or stopping bleeding.
