Help!

I'm 33 weeks 5 days and I had an ultrasound today and they said my baby weighs 5 pounds 5 ounces. Is this okay or is this too much for where I am in my pregnancy. I've heard they can be off by a pound or2. I'm worried that she's going to be big when she's born. Anyone else ever experienced this? I'm just really worried about this. Thanks in advance!
