Ultrasound - Gender Question

Has anyone wanted the gender of the baby to be a surprise, and the tech reference “he” or “she” during the ultrasound? I am 32 weeks along and get ultrasounds every 6 weeks at this point.

The first question our tech asked us was if we knew the gender or not and we let her know no we don’t know and don’t want to know and she also had us look away when she got near the bladder just in case but we noticed she referenced “he” twice throughout the ultrasound. (One time before she got to the bladder and even saw anything and one time after)

My last two babies we knew what we were having but want this one to be a surprise. Since I am 32 weeks I so am upset if she just gave it away to us after waiting this long :( We feel like she saw my chart or something before hand and even though she asked if we wanted to know, just went into it knowing what the gender was and didn’t even realize she was saying it. Some times she’d reference it as baby and other times as he. I’m mad at myself for not just calling her out.

Just curious if anyone’s experienced this and the tech was wrong. Or if maybe they just say this out of habit or if we think she really slipped!
