Good luck with tomorrow but it would be better not to imagine you should lose x amount. You just don't know what factors are in play.
And don't make a big deal of weighing yourself. Its a recipe for disappointment, if not now, later one.
Its great you have not cheated. Keep working on your resolve to avoid doing it. If you feel you want to cheat, have a back up plan so you eat something better instead of something you my regret.
