burning and itching but no weird discharge.

i’m on my period, and a day or 2 before it started i started to itch really bad down there, then it started burning, i made sure i had no abnormal discharge, which i don’t, and it doesn’t smell. i don’t know what this is, but it’s making me super uncomfortable. i don’t know if it’s a yeast infection or a uti or nothing, but i just wanna get it under control.
