What is it?

I've been experiencing an itch near my vagina, mostly clear discharge with a slight pink tint to it, and pain during intercourse. There's no smell to the discharge or me (otherwise my man would have mentioned it this past weekend), and we always use condoms even when I'm on birth control. He was checked beginning of August, so I know he's clean. I made a doctor's appointment for wednesday, but this is still something that's bothering me because I don't know what it is. Anyone else with a similar problem?
