Research Results

I have never had cramps this bad on my monthly.  Ever.  Or so much blood.  OMG.  It's scary.

On Jason's advice, I did some research

Several sites have info, but these are the 2 best summations I found:

Basically, estrogen is stored in the fat cells.  Even more so for women w/ PCOS (which is me).  As you lose weight, estrogen is released, which effects the period.  Eventually, it's supposed to stabilize, but periods can be longer and heavier for a while.  In extreme cases, the bleeding seems to be able to last weeks.

OK, so now it's still annoying, but less scary.
