Sinus troubles! Please help!?

I have been sick for almost 2 months now, thanks to my daughter being in daycare and bringing everything home! Anyway, I was sick before Thanksgiving, with the flu, then I had bronchitis, then I felt a little better, then after Thanksgiving I started to get stuffy and thought I was getting a cold. I just got worse and worse until the beginning of December when my head was so stuffed up I couldn't take it anymore and went to the doctor. Found out I had a sinus infection, my first one ever, and was put on antibiotics. I just finished them on Monday, and I'm still stuffed up, although my snot isn't neon yellow like it was before I went into the doctor, it's clear. So i realize I just may have a cold, but really!? I know that antibiotics don't heal the common cold, but could I have caught a cold while on them and that's what is going on now? Could I have allergies? Could it still be the sinus infection? I'm sure a lot of you will tell me to go back to the doctor, but I've been to the doctor so many times this year between me and my daughter, it's ridiculous! So any input would be appreciated. Thanks!
