Shrinking belly button

Hindi ko pa naririnig yan sa mga kaibigan ko, but honestly it could be normal depending sa weight changes or skin elasticity, like kung bumaba ang weight mo or nag-exercise ka, sometimes ang skin around the belly button area just adjusts. If it's not causing you any pain or itching though, I wouldn't worry too much about it, pero if it keeps changing or may discharge or something, better check with your doctor just to be safe!
