The discharge I've had my whole pregnancy has been white and watery, this however jiggled when i took my panties off.
normally the plug has different colors to it. it might be pink, brown, or even bright red blood smeared in with the clear 'jelly' like consistency. might have been a piece of it though - I have read about lots of girls who lose theirs over a period of a few weeks!
Possibly, sounds more like discharge tho.
