I don't know if it acts as birth control. I would definetly ask a proffesional before I tried that one!! I am hoping to conceive in a couple months after I get my weight down some. Progesterone cream is very safe with pregnancy. I have known people that were prescribed this during because their bodies weren't producing any. I have also found that they are discovering this may aide in protection against birth defects. They have also found it aides in seisure disorders. So does lc woe!! Again they complement each other. So no I haven't heard about the birth control part of progesterone cream.
