Feeling sick. Help me figure out what to do?

Hey everyone, so my dad just recently got sick about 5-6 days ago or so and I caught whatever he has. The problem is - is that I'm trying to figure out what to do as far as treatment and stuff. i have a sore/scratchy/dry throat, stuffy nose, cough, and have been coughing up phlegm. I've been gargling with salt water and drinking ginger root and teas and such but nothing is really helping too much. I know you guys aren't doctors but do you have any home remedies for my symptoms? should I go to the doctor or just wait it out? Thanks so much, 10 points:)
