Please help! Uti???

V

My sides on my back hurt a bit, I pee more often than I usually do without drinking fluids, and I feel like after I pee, I still need to pee more. I’ve had a UTI before but last time it hurt when I peed but it doesn’t hurt right now. I’m going to call the doctor tomorrow but wanted to see if anyone has had these symptoms and it was UTI without it hurting to pee. I’m also on my period right now but it’s about to end
