When I had a bad cough, the medical staff at my hospital strictly advised me not to take any over-the-counter cough syrups as they can be risky during pregnancy. They gave me a safe prescription after checking my chest. It's always best to call your hospital's helpline and ask them clearly.
Didi, thoda sa gunguna paani piyo aur usme thodi haldi mila ke gargle kar lo, bahut aaram milega. Thand se bacho aur bahar ka thanda paani bilkul mat peena. Apne bache ka aur apna dhyan rakho.
I had a dry cough in my second trimester and found that drinking warm water with a little honey and ginger juice really soothed my throat. Since you can't take strong meds easily now, natural warm liquids are your best friend. Just avoid cold items completely for a few days.
Arey, cough can be so annoying during pregnancy because of the pressure on your tummy. Try doing steam inhalation twice a day and drink warm water. If you get a fever or if it doesn't clear up in 3 days, please see your gynac immediately.
