Uc 3d ultrasound question

Marilyn

Has anyone gone for a gender scan at 15 weeks? When I called for prices, the lady told me 15 weeks. When I got my confirmation call, another lady told me 16 weeks..I explained to her that when I called for prices the lady said 15. This lady continued to book the appointment. I've read online that they dont allow before 16 weeks, but then why would she book the appointment. I will be 15+1 weeks!! Help
