fleas/ticks from my puppy?

i’ve had my 11 week old puppy for 4 days now and today i found a little tick (i think) on my desk while i was working, not on her. i freaked out and reached out to the breeder and he advised to use flea/tick shampoo and an ear cleaner. i’ve never had any bugs in my apartment prior so i know it definitely came from her. ive shampoo’d her twice now but i couldn’t find anything on her. this is all new to me and im due to go to the vet this weekend for her vaccination so was thinking to get it checked out then but has anyone experienced the same? do i need to bring in a pest control for my apartment?!
