I hate my scale

I'm blaming the scale. I don't get it. Since we got back from vacation, I've been very good about my eating. And I have nothing to show for it. I start looking like I'm going down a bit and then wham - the scale goes back up. I've been trying to walk at least once a day. I'm watching my weight watchers points and nothing. I don't get it. I feel like right now I'm not going to lose weight unless I get sick and can't eat for several days. Add that to some stuff my body is pulling on me right now and I'm just generally not happy with it.
