Sayang, ini memang boleh happen, dating scan sometimes off by a few days or a week, especially kalau cycle kamu irregular. Tapi sebab ni sensitive dan important, kena tanya doctor dulu sebelum worry , dia boleh explain better based on your full medical history and do proper assessment, okay? Jangan stress dulu, banyak cases macam ni normal je, tapi better get your doctor's professional opinion to be sure. Doakan yang terbaik!
