Extra scan tomorrow- can I ask?

Elysia β€’ Baby girl born Feb 2019!! πŸ‘ΆπŸ’– followed by 3 angel babies πŸ‘Ό

So tomorrow we have a private scan that my husband booked as a surprise and I'll be 14 weeks and 5 days, it's not supposed to be a gender scan as in UK the earliest they do them privately is 16 weeks

But do you think it would be cheeky to ask if they can give us one picture of babys bottom so we can guess ourselves? I know they are developed by 14 weeks and we are supposed to get all scan pics included πŸ™ˆ
