AIBU? Gender + scan

[ruth1104]

So, 20 week scan today and the baby looks well and active, which is fantastic. All along the pregnancy we've said neither of us wanted to know the gender; I wouldn't like that that's all I know about my baby, and I really want to avoid the pinks and blues stuff as much as possible. As much as we are both curious!!! We've had conversations about this with both of our families, some of whom cannot understand why we don't want to know.
So I send a copy of some of our scan pictures to my in laws (who live abroad) and my dh's SIL has emailed back saying she knows what it is (was a neo natal nurse, has apparently done training...) Am I being super sensitive to be annoyed that she's told me this? Now I feel like all the way until the baby's born, she's going to know and I'm not... Which isn't a nice feeling. Relations between DH and his brother are a little strained anyway so I'm probably not going to say anything but would you be annoyed?

I wouldn't honestly pay any attention to her. My friend "knew what it was" because her husband (a GP who had done obstetric training) had "seen" it on the scan. He was wrong :-).

That would annoy me too. If they had been complaining about you not finding out the sex I probably wouldn't have sent any scan photos for this exact reason but it's too late now. Just smile, rise above it and say you're more excited about it being a surprise.

It takes years to train properly as a sonographer and I'd be surprised if a neonatal nurse was that experienced, she deals with babies once they are born.

I would also be surprised if she could see the gender from the scan photo at 20 weeks.

She also has a 50/50 chance of guessing correctly, as do I.

My MW friend 'knew' I was having a girl from scan pics. Her penis and y chromosome beg to differ.

Your sil is being an insufferable arse.

Ignore her. The pic they give you is impossible to tell on for this reason.
Also, unless she outs what she thinks, no one will ever know if she was actually right or not.
I spotted what I though we're a pair of testicles on my 20 week scan, however wasn't brave enough to point this out or say any thing. And actually slightly pissed off that the sonographer didn't tell me to look away, she knew I had a medicine degree (I work as a pathologist). I was right, DS is now 11, but having looked back at scan pic, it is impossible to tell there.
Incidentally I have a friend who was told at the scan she was having a girl so decked her whole nursery in pink. Her 'daughter' has a fine pair of plums and can pee higher up the wall than any girl should be able too!

Haha thanks folks, just wanted to know I had a reason to be peeved! I asked her not to tell us or anyone else and told me she'd 'forget' but since she's no longer a neo natal nurse because of an inability to keep her mouth shut on patient confidentiality issues, I don't have a lot of confidence! Fortunately we're not seeing her before the baby's born, I just hate the thought of all of my in laws knowing before us.. Thanks for the reassurance though!!
