What does it mean to have period twice in one month irritated & itchy vagina?

This could be : Due to any number of things. Usually with irritation and itching around the vaginal area, we tend to think of yeast infections. These can be pretty common. Having 2 menstrual bleeds in one month could still be on the normal spectrum. Pregnancy would be one thing to rule out however , especially if you are sexually active. Hope this was helpful.
