Two gestational sac, one is empty

I am on my 8th wk of pregnancy. I had my transvaginal ultrasound this morning. There was 2 gestational sac, but one if it is empty. The other one has heartbeat already. The doctor asked me to have my ultrasound again after two weeks. Is there a possibility that the embryo will still develop? #emptygestationalsac #pleasehelp #advicepls
