7 weeks scan..

I had a scan today and I was exactly 7 weeks today. I didn't get to have a picture unfortunately. I've seen other people's pictures at 7 weeks though and my baby looked nothing like them. I could see the little hands and feet etc. Looked kind of big for 7 weeks. But I know i can't be further along because I only had sex once the month I conceived. I'm confused.. Has anyone got any 7 weeks scan pictures? Can you post them please?
