I'm going to give the DE a try, have you tried Bentonite clay? I was reading up on DE today and came across clay as well, just wondering if you've tried it?
I hope you recover from your procedure! My period this time still had one day of medium intensity cramping, but it was nothing compared to last month's (or all the other months before that), before I started the iodine. I just wish I had found this information years ago, or that a doctor would have offered this treatment.
