I always put on around 5 lbs at totm...i've come on today =( it's my first week really hope it don't affect my WI result! I don't WI till wednesday but it's really pee'd me off Lol x
i usually put on roughly the same as you when im on. i wouldnt worry about it too much. its your first week.. and you will definitely have lost something and think about it this way... next week your gonna have an even better weigh in as everyone always says to me... try not to think about the numbers too much x
