Is it true that period cycles have a “Bluetooth like effect” where people who live together or spend a lot of time together will have their periods at the same time? I have heard of this phenomenon a few times. Which made me realize, that this has happened to me a few times with friends! Now I am wondering, does this really happen or is it just a mere coincidence?
