want to know the gender

I had my ultrasound for gender reveal at 19 weeks but apparently my baby's private part is still not yet fully developed 😐 my Doctor said "it's still flat" so we initially thought it's a baby girl, so I came back at 23 weeks to make sure it's already 6months of pregnancy. Ended up it's baby boy 🤭🤣 you should atleast check the gender at 23weeks and up 😊
