clutch noise

[clayt74]

Hi all, a quick question.
I have just started to notice that after my ride to work(17miles) that as I creep into the carpark, first gear riding the clutch, I can actually hear the clutch rubbing ( for want of a better word, not as harsh as grinding).
It doesn't do it cold and I don't appear to have any clutch slip or problems changing gear.
Is this the first signs of needing a new clutch? Its done about 38k and I believe its the original clutch.
I am due an oil change which I shall try n get done next weekend and see if the prob persists.
Any thoughts would be gratefully received.

Cheers
