Weight gain ?

Houa • Happily married 👦🏻👶🏻👶🏻| 18
I already gained 16lbs (last time check was yesterday at my appointment) & I'm afraid of gaining too much. I started on the big side before I was pregnant & for my first pregnancy, I gained 43lbs in total. Lost 30lbs of it & im currently 20 weeks 4 days pregnant. Any suggestions? I've been eating so healthy & walking and doing my daily chores/workouts.
