Gender surprise ruined vent

My husband and I have been team green this pregnancy and my last one. It was an amazing surprise for my husband to announce the gender at birth.

I’m a little annoyed I went in for a growth scan and when my midwife gave me the results she told me the baby is small and used the pronoun she. She quickly said “I mean the baby” and kept talking. This was my 4th ultrasound this pregnancy (I’m 31 weeks) during the ultrasound they never told me to look away.

I’m not disappointed just wanted a surprise at birth.
