so about a week ago I had protected sex and the next day felt some discomfort, particularly the vaginal opening as well as clitoris. Within about a day it was red and really swollen as well as itchy. This has continued on to a lesser degree. I have clear discharge (with the exception of the day after i had sex where it was brownish/red tinged - but still clear), a large amount at first, but not so much anymore.

I don't have any bumps or blisters to my knowledge. I am pretty concerned because I have never had general discomfort, swelling or itchiness like this, and am hoping its a yeast infection. I am also taking antibiotics which I started a couple of days before I had sex. Could that have something to do with it?

Thanks for your help!
