Eh, jangan main-main la dengan sakit macam tu at 31+ weeks! Please go see your doctor or go to hospital sekarang juga, okay? Sakit yang menjalar dari pinggang sampai betis tu bukan main, kena check betul-betul whether it's Braxton Hicks, nerve pain, or something else yang kena monitor. A few of my mum friends experienced different types of pain near the end, tapi semua dia kena check with their gynae first, sebab safety lang yang penting. Don't wait, ya, better safe than sorry!
