5+6 ultrasound nothing seen

I just had my dating scan and we did not see anything other than the gestational sac, which measured at 5+6 and was exactly where I thought I was. Share your positive stories on going back two weeks later & seeing a babe! I had a mmc last year so of course I am terrified now. I knew there was a chance of not seeing anything. But I’m so afraid that it could be a blighted ovum. Idk my thoughts are everywhere. I feel pregnant & have no bleeding/spotting at all.
