It’s normal to experience itchiness before, during, or after your period. This itchiness could be felt in the vagina (i.e. inside your body) or on the vulva, which means around your vagina, labia, and general pubic area. There are a number of potential causes for this issue.
Some people experience cyclic yeast infections. Cyclic vulvovaginitis is a burning and itching sensation on the vulva and inside the vagina that occurs at the same stage of every menstrual cycle. Some people may experience it before or during their period. Sexual activity can make it worse Cyclic vulvovaginitis is caused by a yeast infection, often because of a Candida fungus overgrowth. Candida grows naturally in your vagina, which is kept in check by Lactobacillus, or“good bacteria” in the vagina.
other things that can cause itching are bacterial vaganosis …Trichomoniasis…
