Do I have yeast infection?

No discharge, no foul smell, urine is okay and no burning.
I’m just experiencing an itch near the opening of my vagina. I check it. No bumps too but my vaginal opening is really pale and the skin around it is red and itchy.

I buy vagistat and the cream is helping a bit with the itch. Is it okay to continue to use the cream even i’m not sure if it’s yeast infection? Also can I use the suppositories even i’m not sure if I do have yeast infection? Just want to know this first and be sure i’m not just paranoid before going to the doctor.
