Yung back pain sa pregnancy ay super common talaga, nangyari din sa akin kahit sa early months pa lang! It's usually dahil sa weight gain, ang shifting ng center of gravity mo, at ang hormones na nag-relax ng ligaments, basically ang body mo ay nag-aadapt sa buntis, kaya naturally stressed ang muscles sa likod. A few of us mums tried wearing a pregnancy support belt, and honestly it helped so much, especially pag mahaba ang araw at maraming standing or sitting. Make sure din na nag-rest ka regularly, mag-do ng gentle stretches kung kaya mo, at iwasan ang heavy lifting, pero kung talaga namang masakit and affecting your daily life, better check with your OB just to rule out anything serious na kailangan ng attention, sis!
