Midwife isn't sure sonographer's gender determination is correct!

Ah! So I went for an elective ultrasound after not being able to find out our little ones gender at our anatomy scan, and right away the tech said girl! But I showed my midwife today and she said it wasn't clear enough to tell. I'm going back into the ultrasound place and they are checking again for me and I'm going to see another tech but I wanted to get some of your opinions! Every time I looked at the picture I wondered about it but the tech was so sure I decided to go ahead and do our reveal. I hope I don't have to say oops, they were wrong! What do you think?
