Husband disconnected about 🤰

Caroline
Background: I am currently 7 weeks and 2 days pregnant with (either of us-I'm 30 & he's 35) our first baby, we have been married for a month and 5 days.  
I've slept on the couch 1x last week and today I drove away from our home to sleep in my car (for about an hour) because he was yelling at me because I didn't want to go out, as I'm not feeling well, for Easter plans with his family.
I think I'm losing my mind right now and I have no friends with me to talk to about this; they all think we are happy.
I've been having thoughts that this wasn't a good idea to be pregnant, married and concerned that the next time I do something-will be leaving for a much longer time.
Please, help me realize how to be a happy wife?
UPDATE:  We have talked and he's ready to be supportive, I can understand his stresses as we are not $$$, and besides our own wedding we have 3 other weddings (1 is for his BFF on May 5, soon enough in June his older bro where we will be traveling to Florida, upcoming in Sept. is my BFF 's in Arizona) and we are either the Best Man or MOH depending.  Life's hell, but we've agreed we'd rather do it together than without each other.  Thank you all for your advice.  May your years be wonderful.
