I just happened to have my progesterone tested the day before my BFP. It was at 9.18 at 8dpo. My doctor said 9 - 33 was the accepted range for first trimester today when he called to give the results. Seems like I barely am squeezing in!
I also just happened to have a consult with a new ob scheduled for today which went a little differently since I know I'm pregnant now. Did an hcg quant and another progesterone. Have to do another hcg quant on Saturday and get results on Monday.
With my last pregnancy I had the hcg quant done and sadly, it went down and I miscarried. With two miscarriages in the past 9 months I'm going to have to try really hard not to go crazy before Monday and would be glad to hear from anyone in a similar waiting game!
