HCG Level

Brittany
I'm so nervous, I go in tomorrow morning for my 3rd blood draw to check my hcg beta level. My first level came out to be 24 and four days later the second level was 973. I'm so worried since I had a miscarriage in April of this year. I think I'm about 6-7 weeks btw, I could be wrong though since my period before conceiving was kind of irregular.
