Oo, normal yan! A few of us mums here have experienced the same thing when we started Daphne or other hormonal pills while breastfeeding, parang nawala or naging very light ang period namin, at it's usually harmless. Pero since this is about your cycle at hormones, better check with your OB din to make sure everything's okay and na compatible talaga ang pill mo sa breastfeeding, kasi may doctors na prefer certain types for nursing mums.
