Ay, sakit ng likod during pregnancy na especially habang nagtatrabaho, totoo yan, sobrang uncomfortable talaga! What worked for me was taking frequent breaks to stretch, parang every hour I'd stand up and gently arch my back, at nag-invest din ako ng lumbar support pillow na dala ko sa office chair, game-changer talaga yan. Pero honestly, if it's getting worse or affecting your sleep na rin, better to check with your OB kasi sometimes they can recommend safe exercises or even a prenatal massage therapist na makakatulong talaga sa pregnancy-related back pain.
