Hi mrsdolton. With extremely heavy periods, please make sure you're keeping your iron up (red meat, lots of leafy greens, and an iron supplement if necessary). Bleeding in excess of 80ml of liquid is called menorrhagia and might be indicative of a hormonal imbalance. Check out this link on menorrhagia

And while I know Dr. Google can be terrifying, I would still do some research on menorrhagia and natural ways to reverse it. In my case, I'm positive it has been a hormonal imbalance as I had some other symptoms that seemed to confirm this. My hormones are really sensitive and since I m/c'd in November they've been completely wacked out.
I started taking maca this cycle and the other symptoms I mentioned I was experiencing, besides the excessive bleeding (which I won't know about unless I don't fall again this cycle and AF shows), seem to have cleared up. I've also been doing some other things to work on hormone balance and if AF shows I will continue to work with my natural menorrhagia cures. Oh, here's one link I like on how to treat excessive menstrual bleeding:

I've always had heavy periods, but not quite like the way it is now; the amount I've been bleeding is insane. After the births of my children they stopped being so heavy and painful for about a year or so afterward. My mother had this as well. All of my signs and symptoms point to my hormones being off kilter, I've just never made the connections until now.
Menorrhagia is serious business so please try and figure out what's behind yours. It's really worth its weight. GL!
