Eh, perut mengeras time berjalan at 39 weeks tu biasa je, that's Braxton Hicks, contractions yang tidak teratur, so jangan risau sangat! Tapi kalau dia sakit atau keluar air-air, terus pi hospital ye, better safe than sorry at this stage. A few of my mum friends experienced the same thing dekat akhir pregnancy, mostly lepas makan heavy atau dah penat saja. Minum air banyak-banyak and rest abit, if it doesn't ease off or gets worse, jangan delay, call your gynae or pergi nearest hosp. Siap-siap ja, baby boleh come anytime now!
