Aiyoh, baru first baby lagi, memang nervous kan! Honestly I don't know anyone personally with that exact due date, but a few of my mum friends said baby boleh come anytime 2-3 weeks before or after due date, some even 10 days early macam surprise je. Kalau you dah feeling signs like contractions or anything, better pergi check with your gynae or midwife, jangan tunggu until 9/11 exactly okay? All the best, mama!
