First, give it more than 1 week. Let your body take a few weeks to adjust to the change.
Second, it could be because you're leaving so many uneaten points. Yes, the points target may seem like a lot, but we should be making efforts to meet that target (or at least come close to the target) daily while not eating to overstuffed. I would expect that occasional days when you leave uneaten points aren't such a big deal, but the 30 uneaten points would be. Your body needs fuel to keep your metabolism up.
My DH gets a lot of daily points too (over 50). He doesn't eat "diet food" because they don't provide enough points for him to meet his target. When I say "diet food" I mean he eats regular cheddar instead of fat-free/low-fat, regular yogurt instead of fat-free, regular steel cut oats instead of low cal version, etc.
Did you eat a lot of the frozen meals before starting WW? The sodium content of those (depending on how frequently you're eating them) could be accounting for your body holding on to excess water, especially if you weren't eating them regularly before.
"There's no such thing as failure. There's only feedback. Stop judging yourself & start recognizing it for what it is, an entry point for learning. The truth is, if you're not failing then you're not really reaching & really trying. If you don't like the outcome of a situation, learn from it, make corrections & reapproach wiser & stronger until you achieve your goals."
