Red inside my vagina? Help?

Hello :) I have a problem, when I open my vagina lips, on the right ride is red & itchy. There’s no blistering, no puss, no odor. It’s just red & itchy. I know it’s not herpes but I’m not sure what it is. This is the second time this happened & im honestly worried but can’t go to the gyno because I really don’t want my parents knowing. Any suggestions? Please no mean/rude comments 💕

UPDATE: Also I’m on my 6th day of my period. Don’t know if that helps.
