To me, it doesn't look like migraine but I am not a doctor, I am commenting from what I have read and experienced. Migraine usually feels like throbbing headache, feels like heartbeat in the head, at one or more places.
Next time, if it strikes, try Ibuprofen, do not exceed the recommended dose and see if it helps better. Usually NSAIDs help in migraines way better than Paracetamol (Acetaminophen in the US). If you spend a fair amount of time in front of the computer then you should seriously take a look at your posture. If your workplace offers Occupational Therapist consultation, you should get one. Do you get pollen outbreak during this time, if yes, may be this is allergic reaction. Give a try to antihistaminic as well.
Preferably, have a word with your PCP and see what s/he has to say.
