congestion in my head and really bad in my chest!

I got sick this week for the first time in a couple of years. It hit hard, chills, fever, head congestion, chest congestion aches and PAINS. It's been a rough week. I called my dr, they were so busy so I couldn't get in, with the symptoms I gave him he called in an antibiotic. i've been on it since Monday. Along with advil, cold med's and mucinex i'm starting to feel better, but I have a lot of congestion in my head and really bad in my chest. I bring up mucus, but I seem to be having a worse time with my chest. I feel like coughing and it does bring up what's in my chest, which at this time is yellowish/white (more Yellowish) at the same time I can hear my chest wheeze. My question is this, I have not been a smoker all my life, but last year I picked up the nasty habit when my father died. I smoked for about 10-11 months and stopped about 2 weeks ago just before I got sick. Should I be worried or concerned? this is really starting to scare me. I feel foolish to have pick up a bad habit that only affects the health. Health has always been important to me.

Should I give myself more time it's been about 4 days or inform my DR. Thank you
