Only the “SAC” is visible

Aiyoh, I know how scary this feels, a few of us mums went through this juggling between dates and scan findings. It's actually quite normal sebab dating by LMP isn't always 100% accurate, especially kalau cycle irregular or ovulation come later than expected, so the sac size being 6 weeks when you calculated 7+ weeks bukan perkara yang luar biasa. The best thing to do is follow up with your doctor kasi dia assess and maybe do another scan dalam 1-2 minggu to check kalau baby growing well, they'll put your mind at ease much better than anyone else can!

yea. same with me. i was 7w but only sac was visible and the size was 6w. then in 9w baby was visible with heartbeat but still 1week smaller. register buku pink at 13w and doctor asked to revised edd bcs of baby size. i am 24w now, and yes baby is 1week smaller than lmp. and my edd is postponed 1week after the original edd.
