Uti ? Help

So um I occasionally get the feeling of peeing and I can’t .. but it burns so much. I don’t know if it’s a UTI because I never tested myself. This isn’t the first time it happened to me, i get them frequently and it sucks ! I woke up this morning with a burning sensation, and my abdominal area feels funny. I’m on my period so I didn’t have sex. I’m saying this because the previous times I’ve had it , I got it after I had sex ..

why does this happen I’m genuinely confused and concerned.
