NIPPLE DISCHARGE??!!!!!??

Ok so I've been on the pill for a little over a month and I've noticed the occasional dampness on my nipples throughout the day. Earlier tonight I was doing a self breast exam WHEN SOME CLEAR SHIT CAME OUT OF MY NIP NOPS. WHAT THE FUCK. IS THIS NORMAL. DOES THIS HAPPEN. DO I HAVE CANCER. I NEDD SOME HALP. btw I'm 15 and NOT pregnant (too gay for that) I will say tho a couple months ago I was raped by this girl who's rly nasty so I wouldn't be surprised if it was an STI. The discharge is clear with teeny tiny white specks and its kind of sticky but mostly watery
