Covid-19 and pregnancy?

So my son who is 5 started feeling sick yesterday and today he has a fever. He’s been throwing up and coughing but those are the only symptoms that I know he’s having (he’s currently with his dad). Im trying to get his dad to go get him tested but he’s being difficult and saying he doesn’t need it. His dad doesn’t know I am pregnant yet. If my son comes home while he possibly has COVID-19 could I put myself and my unborn baby at serious risk? I may need to take him to get tested myself if his dad won’t. I am not yet vaccinated.
