Catching cold with a headache ?

Possible: But not enough. Would suggest treating your headache and checking your temperature. Viral or bacterial infections may have a subtle, gradual onset and a high level of suspicion is justified. Think also of circumstances, such as sick contacts days prior to symptoms.

Certainly possible: It is possible for a cold to start off with headaches as the first symptoms. For more information on colds, refer: http://www.healthline.com/health/cold-flu?ref=global
