Does anyone face anger issues like me?

I'm in my second trimester and been angry lately, over 5 days continuously. Reason is the elderly men! Both my husband's grand father and my father-in-law are kind of annoying because of their erratic and insensitive behavior. The latter is too childish in nature and my private life is at stake! He enters the room without knocking the door and behaves like a 16 year old teenager. Now, my in-laws are on a visit to our home and would be here for a few months. I'm really angry and upset that my pregnancy is going in a disastrous way! I wanna be alone all by myself and take care of myself! My husband doesn't seem to encourage a word against them because he has taken them for as-it-is. He says, "They're not gonna change. It's you who needs to adapt!" Makes me sad. My mother-in-law is adorable. I love her. I just want her but no one else.
