Overweight

Hi everyone I am brand new to this group just found out I'm pregnant Thursday going to the doctor tomorrow. First baby with my husband. I was wanting to ask something maybe some of you ladies can help. I am very overweight. I am wanting to lose some weight a healthy way before my baby starts growing. I don't want to be a morbidly obese mom. Has anyone done this? I don't want to harm my baby. I just want to do it a very healthy way. Any advice would be much appreciated!

Thanks,

Ciaran
