Dear BeingGirl Experts,
I wanted to know why some family members get their period at the same time.
This is a phenomenon known as menstrual synchrony. It occurs when women share the same living space. Each woman secretes substances called pheromones. These are scents (chemical means of communication) that are undetectable to our conscious sense of smell. However the female who produces the strongest pheromones causes the other females menstrual cycles to move closer to hers.
Hope this is helpful
