All the info you got was really good so please don't stress yourself out. Wait till you get to weigh in and see what the numbers are and you can talk it out with your coach. Stressing will not help. I have been going on the scale just for fun at home and NOTHING is consistant. One weigh-in it matched my coaches scale and one it didn't. I go on 3 or 4 times a day and every single time it is a different number in a 5 pound range. I do not let any of the numbers get to me and just wait for "official" weigh-in. And really even the official weight is relative as it depends on what time of day you are going. Don't forget about those inches too especially on your frame those are going to add up and show. Your clothes will be falling off soon.
I just upped my ticker by 41 lbs since April. Time to do something about it.
