Oo, normal lang yan mommy! Karamihan sa amin na nabuntis, lalo na towards second at third trimester, namimigay yung tiyan sa iba't ibang sides depende sa position ng baby at kung saan umiikot siya, kaya minsan mas tigas sa kanang side, minsan sa kaliwa. A few of us tried changing positions, marami ring massage or stretching to ease the tightness, pero honestly it comes and goes lang talaga. Pero kung medyo concerned ka pa rin or kung sobrang sakit or sobrang tigas, mas safe na i-mention mo sa OB mo just to be sure, okay? Take care!
