Oo, naranasan ko na yan! Usually it's ligament pain lang, lalo na pag tumaas ka bigla or nagbago ng posisyon, pero since pregnant ka kasi lumalaki ang belly at nag-stretch ang muscles natin. A few of us moms noticed ito ay normal especially second and third trimester, pero if it's sharp, persistent, or may spotting or other symptoms, better check with your OB agad lang para peace of mind mo, mas okay na sigurado na lahat okay with baby.
