Should i worry??

Patricia • 24 yr old wife and mama👱‍♀️ to a handsome toddler👱‍♂️and our rainbow baby on the way🌈

My 5 year old just started running fever and coughing out of no where and I'm worried about how it might effect myself and my unborn baby. I am 33 weeks and 1 day pregnant today. Normally when my son gets sick I always get sick a few days to a week later. Should I let my dr know?? Or should I just wait it all out?? Our baby shower is also in 6 days in a public play zone. Thanks for all advice!!!
