Oo normal yan sa third trimester, mommy! Ang ligament pain (round ligament pain) and pelvic pressure are super common sa stage mo na, maraming kaibigan ko na-experience din yan pagbangon, parang may duling or sharp sensation sa groin area kaya mas mapapabuti kung bumangon nang mabagal, legs down first bago dumikit sa sahig. But since you're already 36 weeks, best to mention it sa OB mo next visit para sure lang na nothing else is going on, especially if it's getting worse or may bleeding. Hang in there, malapit na!
