Transvaginal sonogram help


Hello, I am not sure if this is the right group but was hoping for some support. I went today for my first dr appt and they did a transvaginal sonogram, we saw a well formed sac but not much else. My dr doesn’t believe anything is wrong but maybe I’m too early. I am supposed to be 6w 4d but he’s thinking I ovulated later. I go back in a week to see if anything pops up. Can someone share their experience if you went through this?
