Low progesterone. Nervous!

So went on Wednesday for my 2nd blood test. Progesterone level went from 11.6 to 9.1

They gave me a prescription for 100mg pills when they got the 11.6 result but made it 200mg once they got the results it went down.

I don’t have my ultrasound or another appointment till June 29th in 2 weeks. Super nervous and hoping everything works out!

Will the pills make my progesterone go up?! Has anyone else had this happen and everything was fine? In October I had a miscarriage so am super nervous about everything being okay this time around.
