Can i still drive my car?

So I have a Honda Civic with a blown head gasket a mechanic confirmed with a chemical test. When I check the dipstick and the Oil cap I see no signs of coolant mixing with oil I even took the valve cover off and no signs of water whatsoever, although after the car warms up there's bubbles coming through the hose in the coolant reservoir. Not a lot maybe a bubble every 10 seconds. My question is can I still drive my car for another two weeks until I have time to fix it? Or am I risking messing up the engine?
