Ay, totally normal yan, mama! A few of us sa barkada namin didn't feel much movement or show until around 18-20 weeks pa lang, at parang ang baba-baba ng anxiety namin nang ganitong stage. Pero kung worried ka talaga or feel mo talagang may different, best to check with your OB lang para peace of mind mo, walang masama sa pag-confirm na lahat okay sa baby mo. Kaya mo yan, mama!
