Should I be worried about severe headaches while on 60mg Accutane daily?

I am on my 5-6th month of Accutane now and have struggled with headaches since the start. Recently, I have had a severe pressure like headache that sends me close to being sick. I would almost put it down to a migraine, but since I don’t suffer from them usually I wouldn’t know. Could this headache be from my Accutane and if so, could it be serious?
