Update on spotting and hcg

So my dr put me on progesterone suppositories as a precaution because of a previous miscarriage. I am currently 6wks+2 days and received my hcg update and it was 47811 so I'm feeling much better now that those results are positive. I will be going for another blood test on Tuesday and an ultrasound next Saturday. I just want to hear a heartbeat and get passed the anxiousness of the first trimester.
