Does being pregnant make you go crazy?!?

I am seriously going crazy. Certain things that usually don't bother me bother me to the max. I can barley be around my SO for more than 5 mins without getting severely annoyed by him. I feel so bitchy , irratable and angry. Idk if this because of certain things in life that are stressing me out or if it's just hormones. It's driving me crazy that I'm going crazy . Ladies! Help me!!!!!!!!
