I would like to know if my puppy had parvo?

my dog had 8 puppies, it was her first litter and the other day one of the puppies got sick and a few days earlier it was fine. well the puppy didnt eat and didnt drink. it didnt have any energy. well this was my first time with a dog who had pups but the pregnancy was accidental. she got out one day and bam she was prego. well my puppy died and i felt so bad cuz i didnt know what to do. they are 5 weeks old and the vet said i cant vaccnate them till they are 6 weeks old or worm them. wondered if it was parvo and if my other pups could get it. the pup had slime in her poop then blood and then she was vomiting, but also i was putting one of those like swiffer mops together and the canister broke on the floor. i had to go in the back of the house to get a towel and i wonder if the puppy drank some of it. so i dont know what to do. plz help.
