Well with my son I had my first ultrasound at 5w6d and he was a peanut with a hb, this pregnancy just showed a small sac but he said it looks around 5 weeks.

I was 5 weeks but the sac was measuring at 4 and a half weeks I was really worried too, there was no heartbeat and couldn't see much! But went for another two weeks later and seen a little bean still very small tho!
Try not to stress it's normal not to see much at that stage, wait a couple of weeks and you will see you baby more clearly :)
That's my 5 weeks 0 days ultrasound, we saw amniotic fluid and a gestational sac. The ultrasound tech wrote in his report that he saw a fetal pole but as you can see there's nothing. We saw bean at 8 weeks 4 days :)
