It doesn't surprise me that raw affects our hormones. Many long term raw girls get very easy periods. But stopping is a sign something else is happening.
Is your hair and nails beautiful? If not, something is out of wack.
Have you looked into sleeping grounded and under EMF blocking sheets? This really helps because you suck up negative electrons which detox you in your sleep (many say menstruation is linked to detox but don't know exactly how), but also protect glands that make hormones. Balanced hormones mean happy periods. I love my sleep now.
It might help:)
