What do you do if you are feeling unwell during pregnancy?

Hi all, this is my first time. I’m 6 weeks 1 day and my first appt will be coming Thursday. But I feel a little under the weather today as I woke up with slight sore throat. Should I get OTC medicine or wait till my Thursday appt to check with my gynae? Or should I go to any nearest GP in the meantime? Not sure which one will be better. Any suggestion mummies?
