Too early?

Molly

I had an ultrasound on Friday. I should have been a little over 7 weeks based on LMP. The sac measured at 6w5d but there wasn’t any visible baby. There was a yolk sac that was seen but that was it. Anyone have a positive outcome with this? I did a blood draw for HCG to see where those numbers are at but I’m nervous. I’ve suffered three losses before this pregnancy and I can’t fathom going through it again.
