If my levels are high enough of progesterone, will taking progesterone pills harm me? is there a such thing at too much

Yes there is such a.: Prosterone is a chemical/hormone. It is the main ingredient in depo-prover, an injectable birth control which provides much higher than your natural level to "shut-off" ovulation and overide the effect of your estrogen. Does this have side effects--sure it does. My principle is: if you don't need it, don't use it. Use smallest effective dose when needed. Consult doc. Good luck.
