Maybe anything that upsets the normal estrogen/progesterone levels or cycles is risky.
Those new birth control pills that allow girls to stop having periods seem a little risky to me....it just ain’t normal.
Would I imagine be a welcome respite from the hassle though.
I think this is probably what killed Elizabeth Edwards. She gave birth at age 48 and again at 50. Speculation indicated she may have used doner eggs, but the actual circumstances of conception have never been revealed.
