All I can say, as ever, is regardless of the outcome of a scan, it only means the bitch is in whelp, or not, AT THE TIME OF THE SCAN. It does not mean the bitch will carry to term.
Again, as I've said many times before when this subject comes up here, I never bothered with scans, preferring to wait it out but I suppose I was lucky that I had no need to know ahead of time. I feel lif I had gone with scans, as so many do today, even if I'd been told there was no pregnancy, I'd still have been looking come the due date!
