Doctor after I had an unprotected exposure. I got tested myself after one month with duo 4gen test. That came negative. After that I had my partner antibody test. That too came out negative. Do not know about his last exposure. After 93 days I had mine antibody test. That too came out negative. But after 100th day of exposure. I develop sore throat. Not much painful. But scratchy type. Am I at risk again? Please tell.
