need help desperately

Need some advice! I've been dealing with a bad sore throat and a horrible headache for a week now and in the last day or 2 I've developed a cough. All the Tylenol, hot tea with honey, and cough drops in the world have done nothing to help. Neither have ice packs on my head. Warm baths. Nothing. I need ideas of safe things to take during pregnancy. Hit me! Please! I don't know how much more of this I can take. I'm 17 weeks 3 days and I work full time I really can't be sick right now.
