No fetal pole but 27,000 hcg level


Hello, so last week I went in for an ultrasound and my app said I was 7w6d but when my doc did the ultrasound she said the gestational size was 5w6days but there was no fetal pole. I had my hcg level check that day and I was 27,000. I’ve had 4 miscarriages and 1 live birth so I’m always so nervous. Has this this ever happened to you and what was the result?
