Would you believe the US tech

Kylie

Went for my 20 week US yesterday and said very specifically we don’t want to know gender so please don’t say he or she or him/her. US tech said oh I just say baby…literally 2 min later she said “baby is in a good position to take a look at him”. I’m really upset that she may have ruined our surprise. This is my last pregnancy and I really didn’t want to know. Would you believe what she said to be the gender or do US techs just say one sex without actually referring to the real gender.
