Sick and pregnant

Yesterday I started feeling a sore throat and today i am extremely exhausted. My 2 year has had congestion and a small cough for 2 days. I haven’t had any congestion just the sore throat and exhaustion. I took an at home covid test it was negative. But also have heard the test take a few days to show positive. ( I know not every little sickness is covid so please don’t lecture me) Ive been lucky to not have covid so far so I don’t know what to expect or look for and all symptoms are different. Could this be the start of something or just a minor cold?
