Need help asap! PLEASE RESPOND!!

I just took my bra off and noticed a new freckle on my left areola. Ive never seen this freckle before.

What could this be? Im 16 and freaking out. Ive just recently been to the docter and stuff so i know its not cancer. So what could it be/mean?

Its not a dark dark brown/opaque like a normal freckle its kind of like a faded brown splotch that faintly resembles a circle. Id say the color is a medium brow/light brown color
