3 wks out and 2oz gain

This is fluid stuff. Relax. And STAY OFF THE SCALE.

Seriously?  2 OUNCES?  Girl, you could shave your legs and lose 2 ounces! Don't worry about ounces, unless you're gaining 16 of them!  

TWO OUNCES? Please tell me you are complaining about two POUNDS, not two ounces.

You need to relax, concentrate on healing and hydration. You will be just fine. It takes time to heal and for your body to adjust to the new realities.

Two ounces?

Are you serious?

I gain five pounds in a day.

Throw the scale out the window and concentrate on your nutrition.
