That's me, two weeks on, two off. Been that way for a couple of years now (I'm 46). I'm just hoping we don't do that "dorm room thing," where everyone's period syncs, because that would suck for my little girl.
My sisters are 10 and 7 years older than I am and they went through this too. In fact, my oldest sister had hers non-stop for a while. I think it's all gone now.
