Is anyone worried in gaining a lot of weight?

Ju

I am barley going on 2 months but I don’t know why I’m feeling very hungry all the time. This is my third child. And I don’t want to gain a lot of weight because si had lost a few before getting pregnant. I need advise on what workouts to do. I usually walk for 1 hour every morning. But the food is driving me nuts! I want to eat everything 🤫🤤😩
