First ultrasound at 18 weeks??

Cassandra
This is my first pregnancy and I have my first appointment on August 10th (they wouldn't see me until I'm 8-10 weeks). I was told when I made the appointment that they do not schedule the first ultrasound until 18 weeks unless there seems to be a complication. I've read online that this is normal for some doctors to do, but I'm wondering if anyone on here is in the same boat??
