Uy, relate ako dito, third trimester ko dami na talaga ng back pain! A few of us mums tried wearing a pregnancy support belt (game-changer talaga), plus yung pelvic exercises and stretching every morning, at mas nag-improve. Siguro try din sleeping on your side with a pillow between your knees, kasi yan ang easiest position na hindi so demanding sa back. But honestly, best mo rin i-mention sa doctor mo during your check-up para ma-rule out kung may ibang reason, at baka may specific exercises na rec nila for your situation. How far along ka na?
