Oo, totally normal pa rin, mommy! Sa 18 weeks pa lang, ang uterus mo ay lumalaki at pushing pa lang sa organs mo kaya super common ang bloating, a few of us sa barkada experienced it throughout pregnancy, hindi lang sa early weeks. Pero if it's accompanied ng severe pain, difficulty breathing, or constipation na hindi maayos, better check with your OB lang to be safe, okay?
