12 week scan pic

Hi everyone! This is my 12 week scan pic which I think is a really clear photo, baby didn’t want to be moved much stayed lay asleep pretty much the whole way through lol 💖 since I’ve shown people I’ve had at least three comments off different people on how the baby looks big on the photo and am I sure I’m not further along etc? I actually measured 12 weeks 2 days, when I should of originally been 13 weeks on the day of the scan so got put behind by 5 days, and there was no mention of the baby measuring big. Just wondered what everyone’s thoughts was and if you had any scan pics like mine ? I assumed it had just been zoomed in xx
