5w6d no fetal pole

I had a scan today 5w6d no fetal pole only a ges sac and yolk sac. My dr said it’s still in normal range but she is concerned. Ugh have to wait til next week for another scan any body else have this with a good outcome. This was done through <a href="https://glowing.com/glow-fertility-program">ivf</a> so I know the dates are correct.
