I really understand your worry, three months of cough at pregnant pa is genuinely stressful. But honestly, if the doctor's suggesting admission, that's worth taking seriously; a persistent cough na ganyan for that long could mean something needs proper checking, especially since the antibiotics didn't work. Please go get a second opinion or follow up with your OB specifically about safe options during pregnancy, there ARE cough remedies that doctors approve for moms, kaya huwag na mag-self-treat pa, okay? Your baby and your health matter more than avoiding the hospital visit.
