confusing ultrasound

So I got this transabdominal ultrasound 4 days ago when I thought I was 7 weeks 5 days at a sonogram place by my house, and they measured me at 5 weeks 3 days. (Which is weird because I ovulated may 7th and got my bfp on may 19th)
So I know the black spot is the gestational sac, what are the white areas next to it?
