V.P.
I was just reading up on this yesterday because my period have gotten very heavy (I'm 43), and I learned about all the different options. But I understand huge amounts of cod liver oil, especially with high amounts of vitamin A, really controls it. I haven't tried it yet, but I know my periods were much better when I was regularly taking fish oil, so I'll be trying that before I take more invasive steps. Google heavy period and nutrition or cod liver oil.
