Should I get my 21 month old tested for Covid?

Hey guys! I know this might seem like a silly question for some people but I’m not the type of person who runs to the doctor every time my kids get a runny nose or cough. I like to let their bodies try to fight it off to help build their immune system, obviously I will take them to the doc if I feel it’s getting worse or not eating or something along those lines. Well my almost 2 year old started getting a runny nose and slight cough today, no fever. With everything going on I’m just wondering if I should try to get him in to the doc to get tested? He had the exact symptoms about a month ago from teething. Just wondering what you guys thought. Thanks!
