Hcg levels dropping

Jasmina

I went to the doctor's few days ago to what I calculated 8 weeks and saw no baby in the yolk sac. She told me it could be possible that I ovulated late. We did a blood test 48 hours of each other. My levels of hcg dropped from 1300 to 1200. Does this mean I will have a miscarriage or no? Please help :(
