Everyone is familiar with the chat about girls' periods syncing up when they spend a significant amount of time together.

There's something kind of cool about that thought. It makes you kinda wanna light some candles, hold hands and bleed as a single unit, right? WELL blow those candles out right NOW because apparently that's all a bunch of BS. 

Okay, so maybe syncing with your galfriends isn't quite so spiritually enlightening but the idea of it has always been sort of cool. But according to science...nope...that's not a thing.

Glamour reports that the people at the period-tracking app Clue teamed up with the University of Oxford to figure out whether menstrual syncing is actually a thing and they found out it's really not.

In fact, women in the study actually got pretty out of sync with their closest friends during research. 

Glamour reports researchers looked at 360 pairs of close-knit women, including friends, roommates, sisters, partners and more. In 273 of the 360 pairs, their cycles were actually farther apart at the end of the three-month study period than when the study began, meaning their cycles didn't sync together, they migrated apart.

Contrary to what you might have expected, women who lived together during the research were actually found to have diverging cycles, not converging ones.

Clue data scientist Marija Vlajic told Glamour math and hope are behind the common misconception that menstruates sync up. Because cycle lengths can vary, Marija said general patterns could make your period sync with a friend for a short time, but that doesn't mean you're actually menstruating together.

"Say I get my period today and you get your period in 10 days. At this point, we differ by 10 days, and say that your cycle is two days shorter than mine. So then, when we get our next cycle, the difference will only be eight days," she said.

And when we hear that we get excited and think everything's lining up and the moon and stars affect us when really....nah.

"It can be very emotional and very exciting when you notice that you and your friend kind of sync, but it's important to look at it from the more rational side," Marija said.

Oh. Well, we know we've still got a special connection with our girlfriends!
