Hay, normal yan mommy! At 38 weeks, yung ligaments mo ay nag-stretch na ng sobra and the baby is getting heavier, kaya common talaga yung side pain na yan, lalo na if you've been active or nag-lie on one side ng matagal. A few of us moms experienced the same thing weeks before we delivered, pero para malabuhan mo talaga if it's just ligament pain or something else, better check with your OB na, especially if it's sharp or tuluy-tuloy.
