I ve been recovering from a cold, and was feeling better. The past two nights, however, I ve developed a cough that I didn t have previously. And my throat gets terribly sore at night. Once I m up and moving around, everything starts to clear out a bit. I felt okay by yesterday afternoon. But the mucus settled in more firmly last night, and I was coughing up quite a bit of thick mucus this morning. I feel more fatigued this morning, and there s pressure in the roof of my mouth, and across the bridge of my nose (not painful, no fever). I have been taking Robitussin CF and Mucinex. I am also 24 week pregnant.
