Hcg levels high, but no heartbeat

Jennifer
I am 6 weeks 4 days pregnant. I went for my first ultrasound, and they found no heartbeat. Dr. said he could still be really early. She did bloodwork and I got the call today saying that my hCG levels were high. I have to go for another blood test and Sunday, then Monday another ultrasound. Has anybody had this happen to them and everything was okay or not okay? Trying to be prepared.  I am praying everything will be okay. Leaving it in gods hands.
