It's a mystery

I went for my appointment with the intake nurse yesterday and after going over my labs and medical history, she said there is no way I could have conceived with my levels. My progesterone lab on 10/1 was <0.5 which is equal to post-menopausal levels. I conceived less than a week after this lab was taken. As a precaution, they put me on prometrium suppositories and baby aspirin. My insurance would not pay for a lab during pregnancy of my progesterone level at the other doctor(nice, eh?) so they drew one yesterday. I started the prometrium last night. I hope to have the results back today. I do not have another appointment until 12/09 and they will check me on the doppler and ultrasound if needed.
I'm trying much harder to stay on the food plan. I know that could greatly effect my hormone levels and I will choke down whatever I need to until the placenta takes over(at the very least). I am 9 weeks now, symptoms are strong(nausea,tired, etc) and I just pray.
There is no way "science" was responsible for this pregnancy. No charting, clomid, timing, none of it. According to science, I have already went through menopause. I will hold on to hope and faith now. I have no idea what lies ahead.
