Sick or my BC

I started Junel 1/20 FE last night at 10:30 at midnight I woke up with a sore throat and was sweaty. All through today I’ve just had a sore throat but then I started getting cold and checked my temp and it was 99.8. And I’ve heard that if you get on a new medicine and you get a fever it’s bad. Could I have gotten just a cold or is it my body adjusting?
