Burning after using Feminine Wash?!?

I started using an FDS Intimate and Body Wash, and it’s been over a month now. It never caused any discomfort, but yesterday I shaved and today I used the body wash down there and everything past the outer lips is uncomfortable, not too terrible of pain. I just went to pee and it made everything burn!! Anyone know what I could do to help the situation get better/go away??
