Anyone else seem to retain water like crazy?

I'm 16 weeks and I've noticed if I have a high sodium meal I will bloat up like crazy and the scale will jump 5 pounds nearly instantly. A few days of eating right and the weight and bloat go down but I'm just wondering if anyone else is like this? 
Like seriously. I ate McDonald's one night and was up 5 pounds for the next three days. From ONE time! Come on now. Lol
