Ultrasound to check Amniotic Band

at my first ultrasound around the time I was 9 weeks they found what appears to be an Amniotic Band. They never seemed worried and I know it can be nothing and be no danger to the baby. I am now 28 weeks and have another ultrasound tomorrow to check that the band hasn't wrapped around any of the babies limbs. It makes me nervous as this is my first baby but I know no matter what I will love her unconditionally. Going into the ultrasound with high hopes and positive energy that everything no matter what will be ok.
