Losing weight pregnant?


So I’m currently five weeks pregnant! 🤰🥰 This will be our second child. Needless to say we are excited. I’m worried though about my weight. I’m currently 260lbs and 5’6. Yes I know I’m overweight. I’ve been battle this for years and never lost the weight from my son. I guess I wanted to know if there are any overweight moms that were able to lose weight during pregnancy? Is it safe if I do it the right way of course? What types of food changes or diets do people do?
