I have been dealing with sinus congestion and coughing for about 10 weeks now. It started when I was around 10 weeks and now I am 20 weeks. It goes in spurts where I had just a cough and clear phlegm (tmi) to now having more congestion and sinus pressure. My OB thought I may have had a sinus infection and prescribed me antibiotics, but it turns out I am allergic to the amoxicillin so I stopped taking it. I am concerned about taking anything because I feel like this is just a weird side effect of this pregnancy. I have done all the home remedies (humidifier, hot shower, fluids, rest, exercise, diffuser, etc.) Has anyone else dealt with rhinitis or congestion? When will it end? I just can't imagine being congested my whole pregnancy!
