I'm on birth control. I've had trich once and it was cured and went away. Here recently I had a cycle and I noticed I was moist. I figured id stop being moist once my cycle stopped. Well it didn't stop. I continued to have discharge.  A light yellow color. I was using feminine deodorant spray, taking hot baths, and not drinking water which I found can mess up for balance in your vagina.  Yesterday I felt as if I had a diaper rash. Like a constant irritation of my vagina. I looked and noticed I have bumps on my vagina.  Any clue as to what a the cause ? It this just irritation from the moisture?
