Gradual daily weight gain: normal?

Lani

Currently 5 weeks pregnant with first baby.

Is it normal to see the numbers move up every day? I still work out a few times a week, but according to my scale I’ve gained 2 pounds in one week already. I try to right, don’t really eat too much sweets and junk to begin with, but man! If this keeps up, I’ll gain 90 pounds for by the time I’m in labor!
