Sudden weight gain?

KerrieH6

So I happened to weigh myself yesterday and today, and today's weight was about 4 pounds higher than yesterday's. I weighed myself at the same time wearing the same thing on the same scale, so it's not like any of the conditions changed.

I don't feel or look any different, but I think I've read that sudden weight gain can be a concern. 

I actually feel like I've been less hungry the last few weeks and didn't really gain any weight in the 3.5 weeks between my last two appointments.

I'm not sure if this is just a random fluctuation or something I should be worried about. Does anyone know if I should call the doctor about this or wait a few more days?? Thanks!
