A menstrual circle is a type of support group for women who are menstruating. It is a safe space for women to discuss their experiences with menstruation, share tips and advice, and provide emotional support. The goal of a menstrual circle is to create a community of understanding and acceptance around menstruation, and to help women feel more comfortable and empowered during their menstrual cycles. Menstrual circles can be held in person or online, and can be organized by individuals or organizations.
