Sould I be Concerned?

Okay so I 16f have never been pregnant or had sex. But my breast are having a white thing coming out of it (I found out last week after getting out of the shower)

I do take birth control but that is to help with my Period but i unfortunately just recently ran out and haven't gotten a refill for about 3 weeks.

I also have what look like yellow bruises on my breast, but I'm Accident prone. Just wondering if I should worry

Sould I be Concerned?
