Should I be worried about my headaches? (I am on Accutane)

I have been taking Accutane for about a week now. I have been having headaches a lot recently which is not entirely normal for me. However, I also noticed I started getting headaches BEFORE I started the Accutane. I also had a nasty virus the past week which caused me to get a fever, cough, and congestion. The headaches could be due to still getting over this or a mix of everything (and allergies). I am just wondering if I should be worried if this is due to the Accutane or not?
