Hi Tracey,
don't despair - as I said before I keep being stuck for days and then it drops off: At the weekend I went from 71.3kg to 70kg in three days but now I've been there (and gaining 0.1 a day) for 3 days. I have not been cheating, though I have just done 3 PV in a row to be followed by 3 PP now (suited my social life better!!). When I'm brave enough I'll put my curve in my sig and you'll see I seem to be always stuck for maybe 3-5 days before seeing any progress...
Hang on in there!! As the others said you're still losing fat only the scales can't always measure that.
