Worried about chickenpox

I’m 15w3d and my husband was just diagnosed with shingles. I haven’t had direct contact with the spots but we do obviously hug, sleep in the same bed etc. I’ve never had chickenpox and have not been vaccinated. My 1 and 3 year old kiddos have also never had it and neither have been vaccinated. I called my OB to see if I should be concerned but he hasn’t called back yet. Just going to be nervous the next few weeks waiting to see if anything pops up. Isn’t chickenpox while pregnant pretty dangerous?
