I'm wishing you luck. This is not a professional observation, but I would say that if they weigh, for example, two pounds at 6 wks instead of one then you would probably have a 12 lb puppy. Of course, this isn't written in stone - just a guide. If you're getting older, too, it's easier to have a smaller pup because the bigger they are they can really be a bit tough to handle. Hey! Good luck and wishing you the best.
