So for about two days now i have been having an awfully painful (in my chest and throat) cough, i have been bringing up alot of (usually)-thick yellowy mucus just about everytime i cough and a stuffy noise. Also, every now and then i am getting upper back and side pain (but i asume that the pain in my back and sides are from constintly coughing). I am pregnant so i am just needing to know if it is somthing i should be woried about.
