Hcg count

Sarah

So I had my first blood hcg test today and it came back at a 79. I just did a hpt yesterday about a week before my period is due and it was obviously positive. My doctor changed her mind from multiple hcg draws to just needing this one and an us in 4 weeks, saying that this is a healthy number for an early pregnancy. Honestly, I still worry since I had a mmc in July of last year. Should I be worried or just let it go until my appointment on the 1st? Thanks!
