Hello Doctor, kindly help. I had a sore throat at 18 weeks of pregnancy which led todry cough, since then I have been treated with cough expectorants, erythromycin, amoxil and other natural remedies like gargling with warm water and salt, eating bitter kola, drinking hot tea and lime and generally drinking warm water no longer cold. I m now 28 weeks gone in pregnancy an I do not yet had relief, instead it gets so violent and I start to vomit. Please help I am getting really worried now.
