I had my progesterone checked at 5W6D and it was at 12.1. My OB prescribed 400mg of progesterone to be taken vaginally at bed time. Went back at 6W6D for a blood draw and my levels had dropped to 9.2. I have a sonogram in 3 days. Nurse bumped me up to 400 MG morning and bedtime. Feeling very disheartened by progesterone levels. Anyone else have a similar experience?
