How should i use progesterone to fall pregnant?

Progesterone: You need to check with your physician. We check hormone levels thru the entire month to see what is going on all month long and then add in the Progesterone where needed. This is usually day 12-24 of the cycle but varies per patient. This test also let's us know if a patient is more prone to miscarriage and would need Progesterone to maintain their pregnancy.
