Baby's gender

Anyone also has an experience during ultraosund para malaman yung gender pero hindi makuhaan sa scan dahil sa position ni baby? I was told by the Dr. na may nakita siya penis but then nag cross legs si baby.. Hindi na nakuhaan sa scan, so until now palaisipan sakin kung 100 percent sure ba yung sabi nya na feeling nya boy kaso hindi lang nakuhaan sa picture. I really want to know the gender lalo na 4300 php yung CAS ultrasound#firstbaby #pregnancy #advicepls :( Any thoughts?
