Might have Covid

So my bf has recently had breathing problems and a fever lately, I’m not sure how as we barely go out and we always social distance. He’s always around me or somewhere with my family or his family and everybody else is fine he hasn’t been around anybody who’s sick but he went to the er and couldn’t find what’s wrong with him so they suspect he might have Covid so he has to get tested but the earliest we can get him tested is this Thursday and I’m so panicky as we live with my family and there’s so many babies and my parents are high risk due to old age plus I’m pregnant, this has put such a huge weight on my shoulder and my anxiety is through the roof and I’m so worried he caught it and gave it to my family and his family and me as well I really hope corona isn’t his case and something else is what’s wrong
