Understanding progesterone

Hello everyone! I want to start out by saying thank you for being such an amazing community of women to come to when my heart is broken, or if I just don’t know the answer.

I wanted to ask this: In December I had a miscarriage at 8 weeks. For that pregnancy, when I had my levels checked at 6 weeks my progesterone was a 9.4. I was prescribed supplements to try to increase that level, but I ended up miscarrying anyway. The doctor said it could have been due to low progesterone or it could have been other issues with the baby itself. Fast forward to now- I just found out I’m pregnant (only like 4 weeks-ish along) and so I went to get my levels checked. Same. exact. thing. HCG normal for how far along I am, progesterone a 9.6. He has started me on supplements again, but I am (of course) wigging out over here. I’m trying to stay positive since I’m starting the supplements earlier this time. Has anyone had similar levels and had a viable pregnancy?? I’m trying not to stress— but you know I’m stressing 😳
