Expecting Mamas on Progesterone

hello everyone! any mamas-to-be out there using prescribed progesterone supplements because you have had low progesterone?

i found out after my 2nd miscarriage about my progesterone and started it 3 days after ovulation for this pregnancy.

so far i got an HCG drawn 1 day before my missed period (353) and again 2 days after (816)

i know these are hopeful progressions, but what do you ladies think who have had to use progesterone? what have your experiences been?
