Eh sayang, I can't calculate exactly sebab I don't tahu hari apa today lah! But kalau due date mu 15/8/2023, just count the days dari hari ni sampai tarikh tu je, most mums go into labour around that date, tapi ada juga yang early or lambat sikit depending on baby mood! Best you check with your gynae untuk timeline yang paling accurate, especially if ada any concerns, okay?
