EDD for irregular period

Assalam smua nak tanya. Saya ni irregular period. Pastu 2 weeks ago scan kat kk size janin 8w0d which made my edd 13/11/2023. Pastu genap 2w repeat scan kat kk lagi sbab diorng nak confirmkan edd. Bila scan size janin 10w3d (terlebih 3 hari) which made my edd jadi 10/11/2023. Tp kat re-edd tu doctor tulis 13/11/2023 follow edd tu katanya. Mmg camtu eh? Bukan spatutnya 10/11/2024 ke sbab size janin masatu dah 10w3d.
