Uy, yan talaga common sa pregnancy, lalo na pag nagtrabaho ka pa! Ang few of my mum friends, lahat sila nag-complain ng back pain, especially towards the end. Try posture checks throughout the day, magpahinga ng konti, at pag kaya mo, mag-prenatal massage or hot compress, tumutulong talaga, pero honestly, best mo ring i-check with your OB kasi kailangan niyang ma-assess kung normal lang siya or may underlying concern na specific sa pregnancy mo, especially pag wala kang nakatulong na positioning or rest.
