Afraid big baby

I’ve been gaining a lot of weight 2-3 lbs a week and I’m currently 32 weeks pregnant. Nurse told me to be careful don’t want the baby to be too big and have to get csection. At my last appointment doctor said baby has a big stomach and bladder (not in an alarming way). I’m afraid I’m gonna have a big baby. I was 8lbs 9ozs when I was born 🤷🏽‍♀️
