Could there be something wrong?

Okay I had sex for the first time about three days ago. We used a condom, and VCF (vaginal contraceptive film) I also used Plan B just to be safe. Anyways I still kinda hurt down there, and it itches sometimes too, not terribly but enough to concern me. I was curious if I was having a reaction to the spermicides, or it this is totally normal. Furthermore, I was masturbating using this "Climax Bursts" gel and later that morning I had this thick white discharge, then there was none throughout the day, and just now after examining myself I found that this "discharge" is still happening. I was thinking it was because of the stuff I was using to masturbate but I dunno... Should I be concerned? What could possibly be happening? Is this normal?
