No fetal pole experience

La

I went in for my vaginal US and should have been 8w2d (I got a positive opk on 2/27). They saw a gestational sac that measured 6w6d and a yolk sac but no fetal pole. I go back in a week to see if anything changes but my hopes aren’t high.

With my daughter I had an abdominal US and saw her and her Hb at 6w5d

Has this happened to anyone? What was your experience if you don’t mind sharing.
