I went for ultrasound she said I was between 5/6 weeks I didn't get to see much cause her head was in way. She never said anything about seeing heartbeat and I didn't get to see if she tried finding one. What are chances it was just too early? I go back on 11th for follow up cause was so early. She said the fetal pole was starting to develop. Should I be worried? I see so many say they seen heart beat at 6 weeks
