Pregnancy hormones?

Hi everyone this is my first time posting here . I have a question for all the women that may or may not have gone through this ! I am currently 5 months pregnant & this will be my first child. But I have some questions... I am going through a lot at the moment my parents aren’t supporting me as I’d like then too & my partner is constantly arguing with me because of my behavior. He doesn’t seem to get that it’s not my fault I’m getting emotional every second. We’ve been going at it for well over 4 days now. What should I do?
