My three and a half year old son has chicken pox. I am pregnant. What do I do now?

Depends. If you've had chicken pox yourself, don't worry, you're already protected. However, if you've never had chicken-pox or are not sure, call your OB asap. A varicella titer can be drawn, if you have no immunity, vzig (varicella zoster immune globulin) can be given if you're in time. A primary infection in pregnancy can be serious so call your doc now.
DID YOU EVER HAD. Chickenpox yourself? Please let your gyn know asap.
