Infection...Or...?

I already have a doctor's appointment this week. But I've got to ask..

For the last two days, I've been having an itch on the inside of my vagina. I feel kind of dry in the area, and do not have any discharge or smell.

I try to stay away from harsh soaps, i use dove for my body.... and use "free and clear" laundry detergent.

Has anyone else had an experience like this ?
