Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I doubt that Mason is pregnant again, it is too soon. Female cats do go back in to heat quickly but usually around weaning of the kittens. Even if she mated more than once with more than one male the kittens should have been close to each other in gestation. Maybe 1 day apart not 7 days. Her belly could be big from parasites or fluid. If you are truly concerned by the size of her belly have your Vet examine her and possibly take an X-ray to be sure. I hope this helps and I wish you the best!
