Progesterone supplement

Hi I got a call back from my doctor after having done blood work yesterday and said I need to be taking 200mg progesterone 1x daily because my level was 9.5.... According to the first day of my last mens cycle (November 8, 2018), I am 5 weeks and 6 days today. However, I have a strong feeling I ovulated later in the cycle (7days before missed period-). I know this bc I had signs/symptoms of ovulation that certain day and I did not have sex during my fertile week predicted by Glow. So my question is, could my progesterone level be on the lower side because I am not as far along as expected (since I ovulated closer to my period) ?
