Mood swings

I'm 16 weeks pregnant and I'm having REALLY bad mood swings. It's getting to the point to where I don't like who I am becoming... I keep lashing out on my husband when he doesn't deserve it and it's really starting to get to us both. Is there anything I can do to help with this..? I understand that my hormones are completely out of whack but I just thought I'd check to see if anyone else has dealt with this?
