Hello, Thanks for posting, Well it will be much difficult to tell just from your presentation whether it is just common cold or it is bronchitis or pneumonia without actually examining you closely. At the beginning of the symptoms, it could have been common cold but other more serious chest conditions such as rhinobronchitis or pneumonia could have developed. What you should do now, is try to keep warm, drink hot coffee and soup more often, take OTC antihistamine and paracetamol (if fever or headache) for the cold and if the cough is too bad, then you will need some mucolytics to alleviate that. The probably of the infection simply being of viral origin is likely. Since you are pregnant, it is advisable to visit a gynobs for closer review and management in case the infection will want to complicate the pregnancy. Hope this helps and wish you the best
