Tips on helping find out gender

I had my anatomy scan and to find out gender. My husband and I have a gender reveal party planned for Sunday and baby is making us wait longer. I may try and make an appt for Wednesday but I have one for Friday as of now. They told me spicy food and seltzer. Legit had grape soda in my car ready to drink nope didn’t even give the baby time to show it and it was moving more and more touch toes with its hands and all. She didn’t wanna wait and the appt should have lasted an hour only lasted half and hour and recorded heart beat never let us hear it so upset right now. Any other tips of getting baby to show the lovely private parts ?
