Ahhh ini memang confusing! Happen to a few of us juga, dating scan sama last period jauh berbeza. Please check with your doctor which due date to follow , because the dating scan (34 weeks) is usually more accurate than last period estimate, especially kalau cycle sy irregular. The baby weight 2.2kg at 34 weeks is actually reasonable lah, so don't worry too much yet. But you need clarity from your doc on the actual due date, tu important for monitoring baby's growth betul-betul. Jangan stress k, just ask your specialist to confirm which one je!
