Firstly, are you absolutely sure that it's a migraine? Is it like other migraines you've had? Is the pain in the same place?
Things to be aware of: Meningitis symptoms- any sore throat, fever, fluey symptoms, cold limbs, etc?
Subarachnoid haemorrhage: Was the headache very sudden and very severe, like you'd been hit with a hammer, on the back of your head?
If it's a migraine, you've already taken your naratriptan and it's not worked, so you shouldn't take more.
You've also taken too many ibuprofen so you shouldn't take more of that.
Have you taken any paracetamol?
It sounds like perhaps your stomach has gone into stasis, so the drugs you're taking aren't being absorbed.
I find tying a pair of tights tightly around my eyes/forehead and going to sleep helps.
