Gestational sack update

Update: I had my follow up ultrasound today and got to see what we needed! Saw the yolk sac and even saw the little heart beat! I hope this helps someone who goes through this too I feel so much better.

I'm just hoping to hear some experiences from you guys I'm 5 weeks 1 day and had my first scan today and there was a perfect sack but no yolk sack yet. Has anyone had this personally and had everything be ok? Have a follow up on sunday to double check they said by then for sure they'd see it if it was there but now I'm nervous
