BFP...hopefully? Nervous about being on flu

Hello , got my positive yesterday after 3 months of trying. Though it was more of a formal check as I had intuitions after having missed my chums that arrive usually like clockwork. However, I've caught a bad bad cold and also had to drive 3 hours the day before testing. Super nervous , if any of these can have any negative impact ? I'm recovering gradually from the flu now, and have tried to ensure my body temperature doesn't rise. But I still got a headache and slightly clogged chest. Last 3-4 days I had been having running nose and sneezing. Going to the doctor tomorrow anyways. But can any if you say if such common cold / fly/ long drives can cause any threat to such early pregnancy?
