Nurse slipped up

So sad, wanted a surprise and husband sad nurse slipped up and said something- if he heard right he already knows and that upsets me so much. I think if she said “she/her”, than I would have noticed, so I’m pretty sure it’s a boy. Was secretly wanting a girl, so I’m trying lot to cry in my appointment. Heard “my girl” and “pretty girl” right after in the office, though, so maybe it’s a weird sign. Idk just kind of bummed either way that hubby knows. It’s my last baby, so no chance to surprise him (we found out with the first two). ☹️
