Massive headache. MASSIVE.

I'm 15weeks and for the past now tomorrow 3days I've had a massive headache will not go away for nothing Im drinking water like I should I could eat a little bit more but I can bearly move her alone wrote this cause of the screen light on my phone this has happened around 11weeks but only for around 5 hours and I downed some water and when to sleep woke up fine. I'm at my braking point and I don't know what to do. Should a doctor visit be in play next?
