Ay, ang lahat ng yan dapat okay lang since you used the washing machine na at minimal lang ang effort mo, pero yung back pain mo ngayon kailangan mo talaga i-check sa OB mo para sigurado, sometimes 8 weeks pa lang pero ang pregnancy hormones talaga nagsisimula nang mag-loosen ng ligaments, kaya mas vulnerable ang back mo kahit light activities lang. A few of my mum friends naisip nila simple lang ang task nila pero nag-trigger ng lower back pain, so better safe than sorry talaga, lalo na wala pang details kung ano talaga ang cause, could be the baby positioning, could be something else na kailangan attention. Let your doctor know din kung kailan exactly nagsimula ang pain, okay?
