Hi all, I had my 5d FET on 8/10 and today is my first ultrasound appointment. I should be 6w5d now and baby was measured exactly at 6w5d. However, dr said the heartbeat is not strong enough to be picked up by the machine. Although we saw a faint flicker but machine can’t pick it up. She said it’s normal for the frozen embryo to be behind a few days so I’m scheduled to come back in a week. Is that normal?? I cant hold on my tear and start crying after I heard this. I hope to hear more of your experience to see if it’s sort of normal for FET please. Thank you all!
