Am I sick or am I pregnant?

I think I ovulated on the 5th. I'm only guessing because there was only one drop of blood when I wiped. For two weeks I've had sore throat, lightheaded, feel warm, so tired. Now sore muscles and headache. I feel like I have some awful sickness 😷. No vomiting, no sore breasts, no discharge. Work got me to take a covid test. I'm taking a pregnancy test Saturday. I don't know what to think. This also started when we has to wear masks and face shields all day at work.
