LAP Band & Pregnant

I had lap band surgery in 2015, and lost 137 total. I gained around 15lbs over the last year due to a broken leg (car accident), wedding, honeymoon, etc. but I am still well within a normal weight. I am petrified of gaining weight for the baby. I have great support and have a healthy lifestyle (of course I am human) but it’s unnatural for me to see the scale start to go the other direction.

Any tips for how you ladies maintain a healthy lifestyle while pregnant?

Right now, I am in my first trimester and morning sickness is kicking my ass. All I can do is walk for like 30min a day and I am used to a more rigorous workout routine.
