ever since I started having sex, I've been staring at my vagina in the mirror every day, just to see whats happening down there.

1-2 times a day, I notice extra discharge when I pull back my labia. it travels from my vagina (I am assuming) towards my clitoris. it doesnt go on my underwear. it's white, kinda pasty. no strange odor, no pain, no itching, no redness, no anything. should I be concerned? I wish I knew if I had it BEFORE I started having sex. I never looked. now I feel like I freak out over anything. my last period started on the 15th, for anyone that knows about extra discharge around certain times.
