due to the fact that you are pregnant your options are limited. i would also like to ask what you mean by "sinus infection" as a symptom. i would also like to know if you went to a health care provider for further evaluation and if you were given any medications. you can continue to use the neti pot (because that is a saline type of solution and safe for you to use) if you have sinus congestion or stuffiness; however if your sinuses are draining too much that could be causing your cough. i would highly recommend talking to your pharmacist and possibly going to see a health care provider for evaluation.
i’m 15 weeks pregnant and am sick with a sinus infection and cough. i have been using a neti pot but it is not working.
