15 weeks and 3 days Girl for sure?

We had our early gender scan done and after about 30 minutes of looking around (she had her hand down right over her potty area) we were told 100% girl. We have two boys and I'm super hormonal and not used to seeing the girl ultrasounds and wanted to get some opinions. We've already announced she was a girl and have a name and clothes and now im worried at our 20 week anatomy scan she won't be a she for some reason.

Just that they weren't able to see it very clearly means it's more likely to be a girl. That pic looks girly to me and 15+ weeks is a fairly reliable time to tell gender but I understand your concern given that they seemed to have a hard time spotting the goods Anything is possible and I wish they'd have maybe not said 100% for sure just yet, but I do think it's a girl.
