Hello everyone, I'm just wondering if anyone has used natural progesterone/ estrogen creams instead of the bcp for the protocol. I'm currently using natural progesterone for perimenopausal symptoms with good success and would prefer not to stop using it. These natural forms of progesterone/estrogen may not achieve the same response as I believe the progesterone and estrogen used in the bcp is synthetic and doesn't behave exactly the same as the natural forms. Any thoughts/suggestions would be greatly appreciate. All the best to all of you! Shirley
