Ay, hindi ka lang, mommy! A few of us sa group chat namin din nag-complain nito, parang kahit kaunti lang kakainin, ang sakit ng likod after talaga, it's so frustrating. Could be posture while eating, or maybe your body's just reacting differently to pregnancy hormones making everything looser and less supported, kaya mas prone sa back pain, but honestly, best to check with your doctor about this para sure, baka may underlying thing na need i-address. In the meantime, try sitting with back support and maybe some stretches, pero let your OB know talaga, especially if it's persistent!
