I think that I will request progesterone testing. I was tested three days before my loss at 5 weeks and my progesterone was only 2.5 (Beta was 28). We aren't sure if the progesterone was low because the pregnancy wasn't viable or if I miscarried because of low progesterone. I had started bleeding the night before I went in for the repeat blood work and my Beta was 13 and the progesterone was 1.8. I did take early result pregnancy tests at that time, too, though and my lines were not getting darker and they were so faint for being at CD 30/15 DPO. That was why I had called to get blood work ordered.
