Am I being crazy?

So I'm 5 days from my due date. I will admit I am a germaphobe. My SO's nephews birthday party is today at Chuckie Cheese. I was already thinking about staying at home because my ankles and back are killing me. I've worked all week and would appreciate time to just sit with my heating pad and my feet propped up. Then we went to dinner with his parents and found out his niece and nephew are both sick with a virus. I definitely don't want to expose myself to a virus right now, right before my due date. He's upset with me because I'm not going. If I'm honest I'd prefer he doesn't go. I don't want anyone who is sick to be around our baby, including him.
Am I being super crazy?
