my husband thinks I'm a pos...

So my husband and I have been arguing for days now. I have been an emotional wreck and I don't know if my feelings are legitimate or if my 6 week old bump is making me nutty. So honest opinions please. (this is a bunch to read but pleaseeee take the time). So this all started about a week ago when I came home from work ( I am a registered nurse), and he tells me he woke up in the middle of the night with sharp chest pain. I literally got out my stethoscope and blood pressure cuff and took his vitals. All his vitals were normal. I told him it was probably acid reflux or something else completely benign ( he is 34 years old, no history of medical issues and his only family history is hypertension, no heart attacks though.) So I blew it off as nothing. It happened a couple more times and I asked what made the pain better/ worse and if movement bothered it. All his answers pointed to no impending major heart attack. He tells me he wants to go to a doctor for it. I suggested an urgent care, since he currently doesn't have a primary doctor. The following morning I get home from my night shift ready to go get him checked out and he says he doesn't want to go and he wants me to make him a regular doctors appointment. So the following day, I completely forgot to make the appointment!! He literally screamed at me saying I am a selfish PIECE OF SHIT. I made him an appointment after that for the following week. He has pretty much refused to talk to me since. And now, as we prepare our belated Thanksgiving dinner for my family who is coming over in a few hours he continues to tell me what a selfish PIECE OF SHIT I am. I think it is a bit over board. Plus all i want is to be happy... we were going to announce our pregnancy to my parents. They will officially be grandparents. And now I am sitting by myself, puffy eyes and looking gross wishing this day wasn't ruined before it even began. So bottom line, am I being selfish? Or am I being realistic? Personally, i avoid doctors at all costs, so it is kind of just natural for me to not go unless I know I need medication, or my arm is broken in half. Am i just making excuses?? And as a nurse, I know how serious chest pain can be, and also realize the odds of it being cardiac related are very slim but are possible....
