After I had my period,I forgot to change the pad some hrs after the one I used. When I finally did, my Clitoris was so itchy and the edge for itching was so big so I kept on scratching my clitoris and it became so red and sore and so are the walls. I kept on itching and after awhile so a whitish discharge from the clitoris. And after taking antibiotics,it turned color to a dull yellow like mucus.Since Iam at work, I use a pad to stop me from wetting my undies, and this makes my clitoris itchy too.

Are you talking about your vagina? Your clitoris doesn't have "walls" and doesn't have a discharge.

Are you sexually active? Does the discharge have an odor?

Iam sexually active and it does not have an odor!

You may have a yeast infection, or some other kind of infection. The itchiness tells that. Are you able to see a doctor for treatment? No need to be miserable.
