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!
