anger therapy

Does anybody have anger management issues in second trimester? I am a first time mom and am working too. I have recently noticed that I am getting pissed off when things don't happen as they are planned at work and also I am getting annoyed at office politics. They have always been there but I never used to take it to heart so much. Now that I have been advised to stay calm, what Iam doing is get agitated and eat hubby's brain. Such a fool I am!
