Scared of gender being wrong

We did an early ultrasound at 13 weeks 5 days and were told we were having a little girl. We are SO thrilled and she has our heart. I have my 18 week anatomy scan tomorrow and I just can't shake this fear of them saying it's a boy. It's not that I wouldn't love a little boy, I was convinced it was a boy from the beginning and was super excited, but this little girl has taken over my heart and I don't know how I would handle it. Here are my ultrasounds from 13 weeks, what do you all think? Please don't be rude, I am so grateful for this baby I'm just scared.
