Prometrium?

My progesterone dropped from 13.5 13dpo to 10 18dpo (hcg level over 1000 so that’s good). My doctor wouldn’t give me progesterone and said my level was “fine” and didn’t even want to check it. Made me feel crazy for asking. So I said BYE! I just switched doctors and he immediately prescribed me prometrium. Anyone have luck with this? I’m 4 weeks 3 days.
