Oo, normal talaga yan! A few of us moms experienced the same thing during pregnancy, ang skin changes ay part ng process kaya huwag mag-alala. Ang hormones at weight gain ay nakakaaffect ng skin pigmentation, especially sa face, neck, at underarms, so you're not alone dito. Pero kung ang kuntil ay umuusbong ng mabilis o may iba pang changes sa skin na nakakaalala ka, better check with your OB just to be sure everything's okay, okay?
