Weight Gain

Has anyone had any trouble with gaining too much weight? I’ve gained 11 lbs and I’m only 21wks along and my OB is concerned I’m gaining too much too fast :/ I eat healthy home-cooked foods, don’t go out to eat, and am trying to go on walks more.

Before I got pregnant, I would just “diet” by simply eating less but I’m afraid if I do that now, I’ll be depriving my baby 😞 Any tips on preventing too much weight gain and keeping up self-esteem? I feel like such a whale.
