Eh sakit belakang tu memang common dalam pregnancy, especially around that time when baby dah starting to grow and posture kita berubah, tapi better check dengan doctor la just to be safe, a few of my mum friends ada yang kena back pain sama masa ni, so kau tak sorang je, but yang penting nak make sure it's nothing else! Is it like a dull ache or sharp pain, and ada it worse when you sit lama-lama or move certain ways?
