Ambiguous Results

So since I've been home I've been doing some different workouts, which you would think would help a person lose weight, but since I've been home my weight has not changed at all.

I have been restricting and having the same amount of calories as I was having before I got home (with the exception of that one night) so its likely not what I'm eating that's doing it.

Actually I have found a good way to get out of eating dinner (the one meal where my parents are home and encourage me to eat). I just take a nap around dinner time, so i miss dinner and by the time I get up I can just say it's too late to eat. They don't question it much because I've always been a big napper.

I'm thinking that I'm not seeing a change in my weight because I"m putting on muscle from working out, which I suppose I don't mind because I would look better, look thinner and be in better shape despite the lack of  actual weight loss.

That or the scale is messed up. I raise this as a possibility because it has been giving me the exact same number of 129.8 every single time I weigh myself which strikes me as odd. You would think that it would reflect a natural fluctuation in weight, due to things such as hydration and such. I'm going to see if I can find a different scale, because I have been using my sisters scale.

Another possibility, I've hit a plateau. I really hope this is not the case because that would be hard to break out of.

Also, I finally decided to take my measurements:
Bust-36
Waist-27
Hips-37

I don't really know what to make of those measurements. I feel like they are quite large.
Although on a positive note  I am now a small in shirts and dresses, and a medium is too big.
