Eh, macam tu lah babies, kan! Dekat due date pun boleh tiba-tiba decide nak keluar awal, especially kalau baby dah rasa comfortable enough or ada triggers macam stress level mum tinggi. A few of my mum friends had early babies and they said it was like the baby just knew it's time, haha. Ada jugak yang say early contractions at 37-38 weeks tu normal je, so tak perlu panic sangat lagi. Just make sure your hospital bag packed and you're ready, baby will come when baby decides, takde yang boleh force dia unless ada medical reason!
