So I went in for my first ultrasound this week thinking I was 8 weeks based on LMP but the dr said I was just barely 6 weeks and to come back in 10 days for another scan. Meanwhile he ordered blood work to check levels. I was able to view the first round of blood work results online and my progesterone is only measuring at 5.6.  After doing some reading, that has me terribly worried since it's much lower than where I should be for first trimester pregnancy. hCG is above 8800. I don't go back to him until Thursday. Anyone have experience with this? Should I call my dr about progesterone supplements or wait until I see him on Thursday?
