Ultrasound gender?? Help?

Hello,

My boyfriend and I are a bit confused. We recently went to do an anatomy scan. I was 18 weeks +6. During the scan the tech advises us that we are having a girl. But the next day they call to schedule a follow up on the anatomy scan. They stated that nothing is wrong healthwise, but the photos didn't quite come out well enough. Also, during the scan the tech mentioned our baby wasn't being very cooperative. I guess what we want to know is what do you all think? The picture and the tech said it's a girl. But we aren't sure if that's the case anymore. Any feedback would be appreciated.

Sorry if the photo isn't great..
