Can you get your period if you are around someone else who has hers?

While there is no scientific evidence that proves you can physically synchronize your menstrual cycle with someone else's, some studies suggest that women who spend a lot of time together may experience similar cycle lengths. This phenomenon, often referred to as menstrual synchrony, is still debated among researchers. Emotional and environmental factors may influence menstrual cycles, but being around someone who is menstruating does not directly cause you to get your period.
