My puppy seems to have a runny nose?

She is almost 3 months old she has just finished 2 kinds of antibiotics one for kennel cough/urlickia, and one for a very mild case of parvo. She eats and plays fine like there isn't anything wrong she is active and has good color drinks plenty of water and pees and poops normally, she seems to have a runny nose and sneezes but there is no green snot only clear she goes to the vet on Monday(16th) and i am wondering if i should take her sooner i don't want to pay $40 for them to say she is fine if i am going in next week anyway. Has anyone else had puppy prob like this? If so could it just be allergies? We rescued her from the shelter and she is a terrier/chi mix of some sore we think she is more jack russel any ideas from anyone?
