Progesterone levels @ 4 weeks?

Bit of history-suffered a MMC in March of 2019 due to low progesterone. We’ve been actively TTC since. I got a positive on Monday. I just got my bloodwork back from my first draw, which was Tuesday (going this afternoon for second draw.) My progesterone level is an 8.0. I know that’s low...going to see what they say when I go today. Anyone had successful pregnancy after first progesterone level so low? Did you go on suppositories? Did it help? Feeling discouraged.
