Thanks for writing in.
I understand your concern.
Have you tried home remedies
like taking honey for cough
. Even taking steam inhalation will help you to relieve stuffy nose and will relieve cough too.
Salt water gargling also helps to prevent acute attacks of cough.
You can take over the counter cough relievers like dabur honetus/ adulasa which are safe in pregnancy
If your cough still worsens then you need to see your doctor too as you are planned for c - section.
I hope I have answered your query. In case of doubt, feel free to revert back.
