How can I deal with my mood swings? My poor husband....?

I am 16 weeks 3 days pg and I feel like i'm on a roller coaster. Yesterday I was sweeping the kitchen floor and the end of the broom handle fell off and I threw it across the kitchen and yelled at my husband about how I was going to buy a new broom and then I was on the verge of tears because I yelled at him over the broom. This is just rediculous. Any ways of handling all these mood swings??? Haha thanks!
