Pregnancy safe home remedies for severe cold/cough?

I have felt myself getting sick over the last few days starting on Thursday. My SOs boys were here during the week and the little one had a tremendously gross cold and cough. He's 6 1/2 years old which is only a year and a bit younger than my son and I expect the same out of him as anyone else, which is cover your mouth when you sneeze or cough, wash your hands and don't use your arms or shirt as a Kleenex 🤢 It didn't matter how many times I told him and reminded him, he did none of those things and lo and behold I caught his illness 😖 I know there isn't much I can take aside from tylenol but I did read that I could take Mucinex or Sudafed at night, so if this keeps up I may go get some of that but in the interim I have been having Epsom salt soaks for body aches, laying on the heating pad for a few minutes at a time, Vicks Vapor Rub on my feet and chest etc. but I am still absolutely miserable. Is there anything else I can do?
