how many weeks you were before having your first ultrasound?

Hi Ladies!
I will start working soon and my insurance will kick in by the end of June. I will be 17 weeks. Do you think is too late for having my first ultrasound? 
I really can't afford to pay out of pocket. The doctor wants to see me at 6 weeks with no specific reason, just to  make sure the baby is in the uterus. 
What do you ladies raccomends? And how many weeks you were when you had your first ultrasound? ( of course you didn't have any health problem).
Thank you!
