Yes my periods are irregular so I don't know they're coming, but often if I'm feeling inexplicably low and negative a period follows. I'm very sensitive to hormones physically and emotionally (pregnancy was hell). I've talked to both the male T's I've had about 'hormones' but can't bring myself to say period. When I said hormones to T1 he said "are we talking about menstruation?" and I was embarrassed and quickly said "yes" and moved on.
