Unsure of gender 16 weeks scan

Mariam

Hi, so I had my sneak peek test which said girl (I took lots of precautions and the result said sufficient fetal dna was present).

Now at 16+5 ive had fetal health scan which showed baby was OK which is the important thing. But the sonographer has now told me he thinks it's a boy? I didn't see any clear potty shot and he only took one potty shot see below. I'm so confused x
