What can help me control my anger while pregnant?

Idk what has been up with my hormones lately. I'm crying for no reason or over something stupid. And just little things have been making me very upset lately...and its coming out of nowhere! The other day I was talking to my mom and she was watching TV at the same time. TV was very loud and she refused to turn it down so I could here her clearly. And then she complains she can't hear me( even though I'm a loud talker and my mouth is basically eating the phone)after repeaty myself two or three times. I finally screamed at my mom saying "Well turn the f**ing tv down and listen to me damn it!!!" And she got really offended l. She didn't say anything but I can tell I hurt her feelings. Then I was like.." You know what, I gotta go." And hang up. Havnt talked to her all week. How can I control my raging hormones? Because that is not the only time I got angry. I have been getting angry at my DH over NOTHING! I need help, I'm going crazy:'(
