First Appt at 16 weeks

Hello Mummies and Mummies to be, I could only secure my first gynae appointment at 16 weeks with my chosen gynae (she's popular hence the waiting time). This is not my first pregnancy but definitely the longest I will have to wait for the first appt. I am unsure if I should go for an initial scan and where to go about since I already selected a gynae? #advicepls
