Allergies/sick while pregnant

Iv been having a sore throat since Monday, I was at work last Sunday and a girl working my hall was sick with a severe cold. I had to use her help to put residents to bed so I was in close contact with her, the rest of her shift. I’m always using hand sanitizer right as I walk out of the rooms and always washing my hands also. Anyways, I have had this sore throat all week, and then a cough started. Well living in the state I do the weather changes just like my moods. I can’t take Benadryl as my fiancé and I both are allergic to it. The only cold medicine I have been able to take that actually works for me is Tylenol Cold and Flu. I hate honey and I can’t stand the taste of tea as it tastes like dirt to me and makes me gag. I was always a carrier of strep throat and was constantly getting it what seemed like every other month until I was a freshman in high school and finally went to an ENT and had my tonsils removed and only got strep once after having them removed. Any suggestions on what to take or do to help get rid of this besides going to the doctor first? I’m 17 weeks pregnant if that info helps on what I can take to help.
