Your pup just left momma and will cry for many things these next few days. Maybe even longer. I'm surprised the breeder didn't bathe your pup when you picked her up. She'll be just fine. She's young and now you have to focus on building a foundation and start training. I shower my boy once every few months. So it'll be a while before you shower her. She'll be a bit bigger by then and might enjoy it. Enjoy your pup and good luck!!
