6 weeks 3 days

Maria

Hi guys, I had a dating ultrasound yesterday I should be 6 weeks and 3 days. They saw the yolk sac but no fetal pole and the tech said she thinks she sees a heartbeat flutter but it’s so small that she couldn’t say for sure. She said I technically could have ovulated later and I could be earlier than I think. Should I be worried that there was no fetal pole yet? I don’t Go back for another 10 days so I’m freaking out...
