I moved and gained 5 lbs!?

Options
So I just moved into a new apartment (just down the street).. and suddenly my scale is reading a lot higher. I haven't been eating the best but I've been staying approximately in my calorie goal and actually I have been much more active than usual so I am burning more calories. I'd been fairly steadily losing til now and I am "supposed" to be at about 182 but my scale is reading 187.

I know scales are not the best way to track weight loss and there's a lot of factors, such as sodium content, lady times, etc but I was wondering if maybe my scale got mangled during the move somehow? That seems like a more dramatic change than i've seen before.

Anyone have any experience with this? I am also on the 3rd floor and used to be a lot lower at my old place but does that make a big difference?

I'm not sweating it, I'm just keeping on keeping on but I thought I'd ask :)
