I used to have debilitating migraines every day. I couldn't function at all before I started taking my progesterone pills. I am literally half dead if I cannot take my progesterone. I was on the bathroom floor five days a week before I started taking my bioidentical progesterone pills. The idea that it would not be available to me anymore is terrifying. And no, the synthetic form of it does not work for me. It just gives me horrible side effects.
