Progesterone drop but still above normal range?

6 day difference. My hcg Levels Are fantastic, but I’m really concerned about my progesterone levels dropping that much. I know they are still slightly above normal range, but the big drop really concerns me. Getting my levels rechecked on Monday. My level before the one last week was at 59, so it feels like it’s dropping really fast.

I’m on 400mg of oral progesterone, and I was 26 hours without it at that point. 4w2d versus 5w1d
