Weird labia?

TMI warning i guess? Okay so for the past couple days my labia have been kinda burny and itchy, but I was about to start my period so I thought it may just be a weird sign of it. I just checked things out while changing my cup, and the labia near my clit are super red and inflamed, and almost look blistered on the edges? I can’t find anything it could be on google, any of y’all have ideas before I go to the doctor?
