Flicker but no sound of heartbeat

Only people with similar experience please

I went on my 4th scan today. I am supposed to be 9 weeks pregnant according to my ovulation day. I am high risk so they always do early ultrasounds. Baby is not measuring 6w5d

1st scan, sac but no fetal pole.

2nd scan, fetal pole but no heartbeat

3rd scan, flicker but couldn’t get heartbeat

Doctor said things do not look good and pregnancy don’t look very good. She would schedule a D&C but since she saw a flicker she can’t (it would be an abortion) she said I might start bleeding at any time but if not we would have to schedule the d&c

Anyone ever experienced the same thing?
