Would you be upset and hurt if your husband acted this way?

I'm 28.4weeks pregnant with our third child. My oldest is in kindergarten from 7-3, I'm a SAHM with the both of them 24/7 and yes my husband is the only one who works and pays bills. Today after taking our daughter to school and getting home, I started to fix breakfast and felt nauseas. Not uncommon in pregnancy so I fed my youngest and myself and we went to lay down for our nap. When waking up my legs feel really weak. I'm still really nauseas and feel dizzy and faint. My eyes are crossing and I feel like total blah. I tell my husband I don't know what to do and I'm scared because I've never felt this physically. And he acts as if I should know what to do. He won't get off early to come help me or even pick our daughter up from school and miss just an hour of work. I feel lost. I can't go pick her up feeling like this I'm scared to drive. I'll be putting us all at risk of a wreck. We have no family members around and no friends to help out, not that he would be the kind to ask for help anyways. I guess I'm hoping for the best right now.
