Anyone have "mood swings" over nothing?

Anyone had mood swings over nothing and take it out on partner? For the last 3 days Iv been so moody and snappy (like a crazy person) over nothing.. and feel like crying over nothing.  we've been trying to conceive and I'm due on In about a week( I think).. my stomach is bloated, I'm gassy and it feels weird/like full feeling and peeing more.. (don't know if it's because I'm drinking more or cold....)
