After how long do I have to worry. We do not have a follow-up appointment.

Hello, we went to see my 21 month old daughter. She was prescribed clavulin for ear infections and urinary tract infections. We are now half way through the treatment but she wakes up every night when before she didn't always wake up at the same time and sometimes she complains of pain, is it possible that her infection is still present. After how long should I be concerned. We don't have a follow-up appointment. His pee is clear and no smell. I have a baby that drinks a lot, I try to increase the amount of liquid to help the infection but I can't force her to drink either.
