Low progesterone post ovulation?

Joanna

Hey, just had my 2nd natural <a href="https://glowing.com/glow-fertility-program">IUI</a> on Tuesday. Today (Saturday 4dpo) I had my progesterone check and my value was 8.55 (last month it was almost the same). I started progesterone today evening. Should I be concerned with these values? Can I still be pregnant? Is this very low? The nurses just said I ovulated and can start progesterone. We’ve been trying for our second baby since January 2020. I had a miscarriage last December (11 weeks)
