Yeast infection

I think I have a yeast infection I don't know i have the urge to pee and little bit of pee come out no burning & there this irritated sensation around my thighs & butt area & Lady part area and I know I don't have a sexually transmitted disease I'm positive that I don't have non. It just irritates I think maybe razor burn or there's something my lady parts don't like like the shaving cream I have I don't know & TMI I'm not wearing underwear cause it's irritates more tbh I check and I didn't seem no bumps or weird things & my discharge is white & no smell.

Update: I have a pain in my side and the irritation is still there and no weird bumps just annoying irritation & no burning pee & discharge tmi is clearin looking. My aunt think I have uti and I'm getting it check before treatment
