Gender reveal

We found out we are having a girl! My husband is scared a penis might show up when we give birth 😂😂 he wants another ultrasound later to make sure it’s s girl since we have already bought so much girl stuff. I can see it’s a girl clearly but is it possible to look like this at 19w and turn out a boy? Hes got me questioning too now...

Hes just concerned because my doctor said we wouldn’t get anymore ultrasounds after the anatomy one.
