Progesterone suppositories

I'm 24 and have had two miscarriages. I'm currently six weeks pregnant today. My doctor ran hormone level tests work my blood and hcg came to 1,800 something and my progesterone was 10.4. She says my hcg level is fine but she wants progesterone to be at least at 11 at this point. I get another blood draw on Wednesday to ensure my levels continue to rise and was also prescribed progesterone suppositories. I'm really nervous as it is and I'm really concerned my baby is at risk. I just want it all to turn out right this time. Does anyone else have a similar situation?
