Trying to conceive

I became sick Tuesday evening with a sore throat. By the end of the night I had body aches/chills, a headache and a sore throat. It lasted until Wednesday night then it all went away. I don’t feel as if I’m going to start my period and usually my period would have started 2 days ago with how regular my cycle is? I took a test around 6:30 and it was negative. Should I test in the morning?
