HCG/progesterone

Amanda
I need some reassurance... I MC last October and got a BFP on 2/20. My doctor ordered HCG/progesterone on 2/26-it was 305/25.3, two days later my HCG was 503. Is that normal? Trying not to stress... I really want to chill out and enjoy my pregnancy. Any thoughts/advice would be appreciated :)
