Does anyone have an opinion that could help please?

So we had our scan yesterday and our baby was in everyshape, but the legs were crossed! The sonographer told us she thinks its a girl as she didnt see boys bits which are obvious most times and my boyfriends mum agreed after she had 3 boys. Im putting my head away not knowing what to buy😂 We have a gender scan booked for tuesday so we'll find out but im dying to buy!
