I think the problem is that if you have low progesterone (progesterone helps with the lining of the uterus) you either might not be able to get pregnant or you run the risk of having a miscarriage. It looks like the miscarriage part is controversial, but in people who have multiple miscarriages, they sometimes use progesterone cream if this is the cause. When I was telling my neighbor (who is a doctor) about all of this, her fisrt response was that I could just get pregnant to help the hormones. I didn't go into detail about this because she is a family doc and I figured this wasn't her specialty, but I also have been wondering if it would help even everything out.
