Aww mama, yan ang ligament pain, totally normal sa third trimester kasi umabot na yung baby at lumalaki pa, kaya nagstretch yung round ligaments mo sa sides at pababa, lalo na kapag naglalakad or gumagalaw siya! A few of us mommies had the same, sobrang nakakapanic talaga lalo na first time, pero please check with your OB lang para sure at para malieve ka ng worry mo, kasi better safe than sorry especially na malapit na ang labor date mo. In the meantime, rest when you can, wear a maternity support belt if needed, at slow down ang pag-lakad, hindi ka nag-iisa dito, karamihan sa amin naranasan yan around 36 weeks!
