Me or baby?

I am currently 13w2d. In my first trimester, according to my home scale (not digital) I gained about 4 pounds. Seemed like a lot to me, and granted, my appetite was in overdrive for a while. Now I am just starting to feel "fat" even though my home scale says I have only gained about one more pound. I am not sure if this weight and bulk is just me, bloating, or baby. This is my second pregnancy. I am 4 foot 11, and so even just a couple
Pounds really shows up on me in a hurry! Anyone else experiencing this, or have input?
