Help! My husband doesnt understand

So my attitude has been pretty wild during the end of the 2nd trimester to now in the 3rd trimester. I have explained over and over how my hormones make me hulk angry and crazy, but he doesn't understand. I've sent him articles, blog posts and everything I can think of... What's he do? ignore them, and then when I hit the breaking point I tell him how I really feel and I'm the asshole... Maybe I am overreacting, but I feel like if I'm giving you the resources to know why I am acting the way I am than you should meet me halfway and try to understand.

Who has been through this with me? What can I do???
