UTI negative

I am freaking out! I was experiencing some burning when peeing and I spoke with telehealth doctor and he said I had a UTI. I was given a prescription and it seemed to be helping but not completely. I went to Planned parenthood to be sure and she said I didn’t have a yeast infection. I haven’t had sex I’m almost a year. I was tested for tric and gonnorhea right after and it came back negative. I do not have any bumps or anything on my vagina that would indicate herpes. She said she was sending in my swab to the lab. I’m so worried about what it could be.
