Chicken pox early pregnancy?!

Has anyone had or been exposed to chickenpox in early pregnancy? My husband has had shingles for a week, but we’ve been careful and containing it. My son woke up with a spot on his face and now I’m really paranoid he has chickenpox. I know only time will tell, but I am only 8 weeks and know it can be really dangerous. I did receive the vaccine as a child, but never had chickenpox itself. My OB office doesn’t open until tomorrow, so I’m planning on calling them first thing. Has anyone dealt with this in early pregnancy and everything turned out OK? 😢😢😢
