How to lessen UTI discomfort??

Actually it hasn't been confirmed as a UTI yet (went to the doctor today) but a bit uncomfortable nonetheless... burning sensation at the end of peeing that started last week, went away, and came back yesterday. It also burns a bit here and there randomly but that's it. I leave for a weekend vacation tomorrow with my boyfriend who's been away for 2 weeks and this is the worst possible timing😩 I've never had a UTI so don't know what's up but doctor isn't prescribing me any meds until monday when tests come back.. is there anything I can do tonight to make sure it doesn't get worse/stays bearable? I've been drinking cranberry juice and water. I have to drive 3 hours tomorrow and would rather not have this be an issue
