Sti ot uti

I know there’s no way of knowing until I go get checked but I don’t have my appointment until next week and was hoping to hear some input. I have a slight pain after peeing nothing crazy but it’s a uncomfortable sensation today it’s a bit worse after peeing my vag feels off I don’t know how to describe it it feels like full and sore if that makes sense I do also pee more frequently. I don’t have any itchiness or discharge nor smell . I’ve read about uti but don’t think I’ve ever actually had one neither have I had an sti before
