Ay sis, yan normal lang yan sa pregnancy! Ako rin ganyan around 6 months, lalo na pag tumitigil ako or tumatayo, parang rock ang tiyan ko kahit gumagalaw naman ang baby okay lang. A few of us mums tried mag-adjust ng positions, like sitting with good support or doing light stretches, at tumaas ang comfort namin, pero honestly, best check with your OB just to be sure everything's on track, especially pag worried ka pa rin, para peace of mind mo lang.
