Questioning ultrasound tech.. Gender opinions?

Breann

I went to a new obgyn on the 4th, and the ultrasound tech swears I'm a month behind what we'd originally been told (I went in believing I was 15w 3d and that would be my LMP based off the information I gave them). She instantly said I was only 11 weeks before doing any measurements or anything. After the ultrasound was complete she said I would need to schedule to see my doctor next week because this office doesn't have clients meet doctors until 12w.

When I looked at my ultrasound, I saw that it said 16w 0d... I'm just very confused, when I go back this week I will be speaking with my doctor over the matter just wanted to see if any of you have experienced this.

Open to all opinions just truly wanting to see what you all think (:

Also for fun, what gender would you say our little one is?
