UTI or not

Idk if I have a UTI. I’ve been having pelvic pain for like a week. I though it was just because I was ovulating. But my calendar shows my ovulation should be over now. But now it’s pelvic pain and some in my lower back towards the side. Going to have my mom take me to the doctor tomorrow. The last time I felt like this I went to the doctor and they said it was because I’ve been drinking too much water. I don’t have any other symptoms like stinging, bad smell, no discharge or anything.
