It's really strange how that happens but it does. I'd feel sorry for any male in that house !
That only works if they all live together... me and my sisters are different now cause we dont but its to do with hormones and stuff
Thankyou for best answer :-)
their hormones get synchronized
No . i really dnt have idea ..<br />
all women's r dffrnt ... yes ... itz just coincident...
Actually its hormonal, between all woman who spent extended amounts of time together like at school or family members. Believe it or not, its chemical.
It's the aura. When I got my first period, so did my mom. But after a year when I became regular it's now different. Now I ovulate when my mom menstruates.
Oh geez another live one.
