Oo normal yan, mama! Five months pa lang kaya ang body mo ay nag-aadjust pa sa pregnancy, ang ligaments nag-eextend, ang uterus lumalaki, so tummy aches are pretty common sa stage na yan. A few of us mums experienced the same, pero sabi ng iba it helps to rest, stay hydrated, at mag-move around gently para hindi maging ligament pain lang ang problema, pero para sure at peace of mind mo, better check with your OB na rin para ma-rule out if may ibang concern, kasi may times na need natin ng reassurance talaga, diba?
