Oo normal yan, lalo na pag malapit na ang delivery! A few of us mums felt super tight at matigas ang belly around that time, parang stone na talaga kasi ang uterus is preparing na. Usually okay lang yan, but if it's painful, hindi lang tight kundi tumatagal ng mahabang panahon, or may bleeding or spotting, mas better na i-check mo na with your OB para peace of mind lang.
