I highly doubt any vet can predict the week a puppy is born unless it is a very young puppy. My puppies were born on March 9th, so a month before yours and I do not think a vet could guess what week they were born at this point, maybe put them at being around the 5-6 months age but not what week they were actually born.
My puppies are 7 lbs 2 oz and 7 lbs 5 oz and they turned 5 months on Aug 9th. My vet it projecting one puppy to be around 9 lbs and the other to be about 10 lbs. We love them dearly even though they are not tiny little ones.
Good luck with yours and enjoy!
