Sepatutnya 11 weeks tapi bila KK scan, 13 weeks

Eh normal la tu! A few of us went through the same thing, sometimes our last period date tak jadi accurate sangan, especially if cycle kita irregular atau implantation terjadi later than expected. So doc will adjust the due date based on the scan measurements instead, sebab ultrasound is more accurate at this stage. Don't worry, 2 weeks difference is very common and doesn't mean anything's wrong, baby's just measuring ahead, which banyak babies do. Your KK doc will use the 13 weeks dating from now onwards for check-ups and delivery planning.
