Did he get the gender right ?

sar

So I went back for my gender scan at 16 weeks 1 day after he couldn’t tell at 14 weeks 6 days ! He said he didn’t get a good print out picture but that it’s a boy and this is the picture he did get ! Do you think boy or possibly did he get it wrong ? I’m just nervous of telling everyone boy to find out it was wrong! It just looks really small to me for 16 weeks ?
