Hopefully i can help..

Normally with a headgasket fault - you will have alot of white smoke vapour or even a cross contamination between the oil and the coolant so certainly check the oil level to see if thats discoloured "cream coloured" - or can cause an increase in system pressure causing coolant to escape via the expansion tank - It also possible to you may actually have leak on the coolant certainly ensure that is ruled out before actually even stripping the engine cylinder off...the only tests to verfiy either of the above is to do a pressure test on the coolant system aswell as the block dye test both of whch should verfiy either way if the headgasket has gone or not or when the system is pressurized using a pressure tester should highlight whether there is loss in pressure or highlights a leak on the coolant other check to make is the interior passenger/driver footwell and ensure the coolant has leaked out from the heater matrix into the car...but as above considering the engine is overheating/continually needs topped up i wouldnt really recommend continuing to use the vehicle as it is to prevent further damage to the engine if not allready done of course due to overheating issue..I do hope this helps
