Worried

Ladies. So i received a positive hpt at 12dpo. Yesterday at 14dpo i went to have my blood taken. They checked my HCG and my progesterone. They called back today with the results. So I’m only 4 weeks and 2 days. My HCG was 22 and my progesterone was only 10. She ordered a progesterone supplement to start taking tonight. I’m so worried. I had a miscarriage a few years ago and when i got pregnant with my son i had the same thing. I go back Tuesday for more blood draws.
