It is best not to use gynecological cleanser during menstruation. The vagina is prone to odor and itching during menstruation, and the internal resistance of the vagina decreases during menstruation, which can cause bacterial infections. The vagina is a slightly acidic environment that can resist the growth of bacteria, but during menstruation the vagina is alkaline, and the ability to resist bacteria is reduced, which can easily cause infection. Eat foods rich in protein, iron and blood, pay attention to rest during menstruation, and prohibit intercourse.
