Sick and 8wks6days should I worry?

This is my first pregnancy and I work in health care surrounded by sick people. I recently got this strong tickle in my throat that gives me cough attacks which leads to a raw throat. All I do to try and calm it down is some vitamin c drops and water. Should I ride it out or get a check up? I feel fine other than that and lack of sleep. I have my first checkup with my obgyn this coming Friday!  Thank you for any feed back!
