Morning headache with nausea and dry heaving!?

I have been getting headaches in the morning, the pain would wake me and i would get nauseous immediately,I would sit in the bathroom for 30 minutes and dry heave sometimes.The head ache can last for 1-2 days,before it would start by the eyes but now its just everywhere.The pain is usually severe.I am a healthy 15 year old male,this just started this year and has happened 5 times already. I am not sure why this happens.I have been doing home school online for 3 years, I spent a lot of time in front of the computer screen,but hadn't had any problems till this year.Now its summer and I spent very little time in front of the screen and still got a headache,the latest one was strange because it started before I went to sleep.Please help me out,should I make an appointment and see a Doc?
