Oo, totally normal yan! A few of us moms experience that cramping sensation after doing deliveries or exercise, parang ang uterus mo ay nag-aajust pa lang sa pagbabalik nito to normal size, lalo na kung recent pa lang ang DO. Usually it settles within a few days to a week, pero if the cramping is really intense, nag-persist for too long, or may other symptoms like heavy bleeding or fever, better check with your OB na para peace of mind lang, kaya mo yan!
