Hormones make me mad?

I've always had a short temper but it seems to be very short recently. I was reading the texts between my DH and his BFF because my DH said he told his BFF we were pregnant. (BFF is pretty funny usually) after he said his funny stuff my DH said "dealing with (my wife) has been fun. She's been extra moody and that's saying something." I was so pissed but upset too. Anyways how do I be less moody? And pissed?
