Another ultrasound maybe???

I was wondering if you have another ultrasound at the end of your pregnancy. I had my last one at 32 weeks and my baby was 4lbs. Now I'm 37 weeks and wonder if they do another ultrasound to see how bigger she's gotten. I haven't gained a single pound with my pregnancy and my doctor told me at 32 weeks that she "predicts" my daughter will be small but because of no weight gain I'm always worrying about her size and if she's growing fine even though my doctor has said everything seems fine.
