sat here alone crying in the bath

I feel so horrible. My husbands come home and I'm in such a bad mood and he has. No idea why. Norte do I. Just sat alone crying in the bath. Deep down I know why. My AF is 8 days away but I feel maybe it's coming soon! Small cramps in tummy which I never have. But when I'm due on I get pains in top of legs and tonight they are here!!!
