Shall I shan't I?

Afternoon,
I've noticed my slight clutch judder seems to be getting a bit worse (was driving round town though) so do I change it now or wait for it to get really bad?

I'm no mechanical expert but is the most likely cause abuse from the previous owner (Glazing plates)?
Or is it more likely oil contamination?

I suppose what I want to know is if I leave it until it's totally fooked will I be looking at causing more damage with the clutch breaking up?

Ta

make sure there's enuf fluid in it, even bleed it if you feel the need to, if that dunt elp slowly bring the clutch up (with the handbrake on) dunt let it stall, hold it just around the bite point for a while - the idea being to break up any glazing (doubtfull its glazing thou) and to clean orf any contamination

and if that dunt elp get yer spanners out
