For a short-term cough of 4 days, you can try over-the-counter cough syrups depending on the type of cough. For a dry, irritating cough, a soothing syrup like a simple demulcent cough syrup may help. For a wet cough with mucus, an expectorant syrup can help loosen phlegm. In addition, drink warm fluids, honey with water, and do steam inhalation to ease throat irritation.

During pregnancy, especially at 4 months, most coughs are viral and do not require antibiotics, as unnecessary antibiotics can be unsafe for the baby. Some cough syrups may be safe, but you should only take medicines that your doctor specifically approves. Since your cough has lasted 25 days, it is important to see your doctor to check for infections like bronchitis or other causes and get the safest treatment for you and your baby.

A cough that changes with the weather, sometimes wet and sometimes dry, is often due to cold, viral infection, or allergies. To relieve it, you can try steam inhalation, warm fluids, honey with water, and avoiding dust or cold air. For wet cough, medicines that help loosen mucus (expectorants) may be useful, while for dry cough, soothing cough syrups can help reduce irritation.
