Yep, as others have said there's a whole range. For me there is almost no day where I don't have some discharge and normally I get a fair amount (like a teaspoon or so). It ranges for me from clearish mucusy (like a big phlegm wad as lovely of an image as that is) to more of an opaque yogurty/gluish consistancy that ranges from white to slightly yellow.

The other bad sign that others haven't pointed out would be if your discharge gets chunky like the consistancy of ricotta or cottage cheese, i.e. visible chunks. Believe me, you'll know this when you see it. I never thought I would but I got my first and only *knocks on wood* YI a while ago and the difference was incredibly noticable.

Also I'm 24 and have had this kind and level of discharge pretty much since puberty at the ripe old age of 11 as far as I can remember.
