scale inaccurate?

so this morning I weighed myself and went down from 152 to 150.6. I usually try not to hyper focus or obsess over the scale but that seems like a huge jump. is that accurate? can weight fluctuate that much in a day? I didn't work out yesterday and I ate the same things I usually eat. is this an accurate reading? again normally I wouldn't question it but I never drop this much overnight. should I track it like I normally would? I'm fully prepared for the scale to jump up tomorrow which is fine
