Second trimester ultrasound...

Jennifer
Just had my second trimester ultrasound this morning. Baby was healthy and nothing was abnormal thankfully. But baby's legs were either crossed or back was turned to us to absolutely confirm the gender. The technician said the characteristics are most likely a girl but he admitted to being wrong before. 
What are the chances you think of getting another ultrasound? Or request a blood draw? 
We do and our family are really anxious to know for sure if our baby is for surely a girl or if it is a boy. Thank you for anyone that can help out.
