30 weeks pregnant with a sore throat for 10 days?

well i've had a sore throat now for 10 days... I went to the obgyn doctor 5 days ago and they gave me robitussin with codeine, sudifed and throat drops. well i am out of robitussin my throat hasn't gotten any better. i feel like a knife is stabbing my throat, mt phlegm is dark green and super thick. I am starting to see traces of blood in my phlegm and i have had an ear ache for the past two days. I wake up with my eyes stuck together and my eyes run like a faucet. what should i do?
