Kelly,
I hear you!
After Ivy and Noah, my AF came back with a flood and a flurry!
It is horrible and overwhelming.
AF came back when they were 5 months old. I have always been pretty heavy but this is just madness. I bleed heavily for about two weeks, with the last three days more like what I would consider a 'normal period'. The good doctor thinks that my uterus is vascular from everything that has happened with, first William and then Ivy and Noah but he has also investigated for polyps, adhesions etc.
After almost eight months of this I am getting anaemic again and so the doc has put me on huge doses of Mefanic Acid ( the stuff in Ponstan)as it can help reduce blood loss as well as cramping. Last month I only bled for 11 days! It was a small victory.

Hugs to you, I hope that the cramping and bleeding settle down soon. I know how awful it is.
