HELP: UTI

Kenz
i always seem to be getting UTI's. i finished my antibiotics for my last one 5 days ago and I just woke up- it is 3AM- and the familiar burning pain when i pee has returned. 
I am too embarassed to go to the doctor because I forgot to do a pee sample the other dat and the container is still in my room. I know I should go but are there any other treatments?
