headache?

I've been having pressure in my head along with headaches for a while, and I recently got a cold.  I don't know if it is a sinus infection or what.  Today I blew my nose and there was a little bit of blood. Is it a sinus infection, or is it something else?

The blood does not mean much.  It might be a continuation of the viral infection and subsequent inflammation.  It could also be a sinus infection.  If the symptoms persist, it is worth a call to your doctor to determine if this needs further therapy.
