Should I continue to be worried

Hey guys so Monday morning my fiancé and I found out that his sister tested positive for covid. We were just around her this past Saturday. We were in the same room but didn’t make any physical contact. We both feel perfectly fine and even went and got tested Monday night (haven’t gotten results back yet). When I catch even a simple cold it shows and even my allergies you can tell somethings wrong, but I’m so paranoid because even though I feel fine I know being asymptomatic is possible. What do you all think?

Thank you guys so much! Both of our test came back negative 🙏🏽
