Hi, Please stop taking homeopathy and see a good physician.You need to treat this bronchitis urgently because if secondary infection sets in you could have a lot problems. Are you a known asthmatic? Have you been on any medications which you have stopped since getting pregnant. Please get a full evaluation by a physician and get a nebulization, antiinflammatory and decongestants, and if necessary antibiotics from the physician. If chest x ray is felt necessary it can be taken with an abdominal shielding. All the above will not harm your baby.But if you do not take proper treatment, it may affect the pregnancy and the baby. Hope this helps. Regards.
