I had my first doctor’s appointment today i’m 8w1d and everything looked good. Heart rate was 175 and baby was on track. My progesterone levels were 16.80

I just picked my prescriptions up and i was prescribed progesterone 200mg 3 times a day. I had a miscarriage in January and I’m freaking out because my progesterone was 5.85 when i had my first appointment with that pregnancy and i was prescribed progesterone supplements as well.

Has this happened to anyone and everything was okay?
