Anger

Since I’ve found out I was pregnant all my husband and I have done is argue about it. Him nor his family seem excited or supportive about it and it’s making me so angry. We have talks ab it and he says he is but just stressed out with work so he doesn’t show it around me. Every little noise he makes or says sets me off. Tonight we had an explosive fight. How do I get this anger and aggression under control ? This is supposed to be a happy time. Not a time where I’m laying in the other bedroom crying.
