Empty sac

I went to my scan ... only measured 6w 1d with a completely empty sac.. no yolk sac, no baby.. nothing.

Doc wants me to come back in a week but he’s not very optimistic. I had sex one time only following a second trimester loss which was on 2/10 so I would of had to ovulate around then to get pregnant again.

Therefor my dates cant be weeks off.

Did you experience this? If so did you do a D&C (just had one 1/24 & scared so soon may not be good) or the pills?

Thanks.
