Does anyone know if you can take Prolief (all natural progest cream) While pregnant?

There is NO reason to take progesterone supplements of any kind without a doctor's advice, especially if pregnant. Your body should be making its fair share. If you're worried, have a blood test done to check levels, but don't self-medicate with this stuff. I've done it and it's NOT a good idea, and I wasn't even pregnant! Side-effects are awful and in short, it can be dangerous. If you had LPD (or miscarriage from low progesterone) and your doctor is aware of it, then discuss it with them. Certainly don't start this single-handedly.
