Mama, please see your doctor or go to the clinic agad, persistent cough for over a week during pregnancy needs proper checking, hindi lang home remedies ang kailangan. A few of us mums went through this too, and naparanoid kami, pero ang doctor talaga ang makakasabi kung ano exactly ang problema at kung safe ba yung treatment para sa baby mo. Mag-hydrate ka pa while waiting, pero please don't delay the check-up, love. Take care of yourself and baby!
