is this even normal

Is everyday vaginal discharge normal? I have to wear panty liners each day and I found out that it’s a common symptom of pregnancy, but I’ve never even had sex. I’m worried that it might be something else, since no one else in my family experiences it; and we have a total of six girls in my family. Should I be worried? I’ve had this kind of discharge since I began my period my junior year and I’m about to be a college freshman now. I thought it might be because of my diet (I’m vegetarian and gluten-free) but I wasn’t sure, so I thought I’d ask the all-knowing women in Glow :)
