Help nbr !!

My 4 year old had 5 shots 9 days ago including tdap mmr varicella ipv and flaurix. Today he woke up with a rash in between his thighs also on his trunk and a patch on his arm. Also spots on his hands and feet. They don’t hurt they don’t itch they aren’t raised he’s having no shock symptoms. The dr said to wait and see took me out of work for a couple days in case it’s chicken pox. But I’m 11 weeeks pregnant and know if he has chickenpox It’s dangerous for me so I’m trying to stay ahead of it. I’m including a pic please someone tell me what you think I
