Is my number to low?

I had a miscarriage last August at 6 weeks, and my progesterone was a 6 I think. The week before I found out my baby stopped growing, my dr put me on progesterone supplements. Flash forward to now....I’m pregnant again, 5weeks/3 days, and I wanted to get my HCG and progesterone checked, just to be safe. Dr ordered HCG tests but not progesterone. On 2/28 (5 weeks/1day) HCG was 1,312. Got my blood drawn again today (5weeks/3days) and it was 2,662. I know it doubled, which makes me so happy, but that seems low to me! What do you ladies think? I’m gonna call the dr on Monday to get my progesterone checked. My 1st ultrasound is scheduled for 3/14; I’ll be 7weeks/1day.
