Is it true that when females live in the same house...?

Is it true that when two females live surrounded by the same house their menstrual cycles become similar? If this is true, how so? Because me and my mom hold cycles that overlap each other. I start first, and later halfway through mine, she starts, and that's one and the same with lots of women I know and their fellow womanly family member.
