First ultrasound, i’m confused

Fred

Hello everyone, yesterday i went to the docter to have me checked. It’s my first pregnancy so i figured it’s what i had to do when I found out I was pregant.

He did an ultrasound and it looked like this. He said i should come back in 2-3 weeks to see an cardiac activity.

But I’m really confused as I thought I was already 7 weeks pregnant as all the apps say. I know the apps are computerised so not as accurate as real life but I needed some visualization.

My last period begun june 3rd.

Do you think it’s normal? I know you can’t see much, I thought you could maybe see the yolk sac but not very clearly. Could someone maybe help?
