Hi, Welcome to HealthcareMagic forum. I understand your concern and I shall try my best to help you deal with this problem. Laryngitis is usually caused by viral or allergic causes. Uncommonly they might be related to pyogenic organisms. Presence of blood in the phlegm indicates there is some amount of congestion and humidifiers and other treatment suggested will relieve your symptoms. You haven t mentioned if you have fever, breathing difficulties / pus stained phlegm. Relevant investigations like X-ray, complete blood count and others are entailed if you develop these symptoms. Currently as per your description, I do not see any factors to affect the baby. The drugs suggested also would not affect your baby. I expect you to be better in a few days. Hope this suffices. Wish you a speedy recovery. Regards
