How is it that when two or more girls spend time with each other, one gets their MC earlier because the other already has it?

Because when a woman menstruates she emits certain phermones and this sensed by the other women in her company. That becomes integrated and touches off other hormones in a woman's body to signal menstruation such as estrogen and progesterone. This simultaneous cycling of menstrual cycle probably has some type of evolutionary explanation.

It's not actually contagious. The trend of two or more women following the same cycle when they spend time together is something that has been theorized to be similar to the way dog packs are. Female dogs in a pack will notoriously follow the cycle of the "Alpha" female. She has a stronger level of hormones and they react in the "weaker" females. It's so that they (the lower female pack members) don't have a reproductive advantage over her (i.e. if she's not fertile, neither are the other pack females, it helps maintain a balance in the pack) Of course, it's ironic that a theory that has been applied to women is about bitches...

Some physiological mystery, could be that primitive tribal tendencies are at work here, like horses, dogs, cats tend to do the same thing when several females are housed together. Here's some info--A pheromone is any chemical or set of chemicals produced by a living organism that transmits a message to other members of the same species. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Their use among insects has been particularly well documented, although many vertebrates and plants also communicate using pheromones.
A few well-controlled scientific studies have been published suggesting the possibility of pheromones in humans, however. The best-studied case involves the synchronization of menstrual cycles among women based on unconscious odor cues (the so called McClintock effect, named after the primary investigator). This study proposes that there are two types of pheromone involved: "One, produced prior to ovulation, shortens the ovarian cycle, and the second, produced just at ovulation, lengthens the cycle". This is analogous to the Whitten effect [1] [2], a male pheromone mediated modulation of estrus observed in mice. Other studies have suggested that people might be using odor cues associated with the immune system to select mates who are not closely related to themselves.

I don't know how this works, but it does happen. My college roommate and I started having ours together after just a couple of months of living together. I remember her "blaming" me (jokingly) for making her think she was pregnant because her cycle had always been like clock work before we moved in together. Eventually, the closest 6 to 8 suites on our floor started having it at the same time, as well.

I don't think the word is contagious you are looking for. Many women that have the same sleep pattern, work schedule and same routine tend to menstrate on the same cycle. Why this happens i do not know.

I'm a nurse. Some research was done on this. It's something to do with the chemical balances in each womans body. I have the same thing going on in my home.

It's all to do with pheromones... I just did a google search and found a site which sort of explains it - don't think contagious is exactly the right word... http://www.wonderquest.com/pheromone.htm

They say that when women spend lots of time together or live together their cycles sync up. It is a fact.
This is God's way of giving us guys a break from the PMS torture.
If we have 3-4 women/girls in the house we only have to leave town for one episode a month.

Women do inhale hormonal scents of other women and this can change the date of their cycles to match.
