Freaking out Severe Cold/Cough

I had a very bad cold and cough for 2 days and I took my temperature yesterday and it was 100.2. I'm certain the day before was higher, but I couldn't find my thermometer. My fever came down significantly last night to 98.6 which is great, but now I'm worried about my baby, since I read fevers can have a harmful effect even to the point of ending the pregnancy. My first appointment is not until this Thursday. I'll be 8 weeks 4 days by then. Has anyone ever had his and turned out to be okay? 😔
