Well, this gets weirder by the day!!! My period is ALSO a week early (sort of) but it does say on the exante website that it can mess around with them and make them lighter or change times etc.
Even if you lose 1 or 2lbs that's still good and think what you'll lose next week if it's just due to totm!!!! I always find that my scales shift towards the end of the week anyway so I think a 3lb loss for you is my prediction! lol I'm 13.11now so I'm a pound down which I'm pleased about as looking on target for a 2lb loss this week.
Don't let the scales get you down, drink loads of water and just go with it, you KNOW you will lose as you're doing 100%! There's no way you can NOT lose. Have a happy day!
