Help! Jaundice on my breasts. I'm 15?!

Well I'm 15 and I'd say i'v "stopped growing" like I'll probably be this size for the rest of my life. I got my period almost exactly 2 years ago so there's really no way I'm still in puberty. Ever since Sunday i'v had a really bad cold/flu thing and last night I had a fever in the 100's and today no fever but I have laryngitis and bad cough with coughing up brown mucus. Idk if this matters tho. But today in the shower I noticed I have jaundice, or what looks like bruises, on both of my breasts in the SAME EXACT place!! At first I just noticed it on the right boob and thought oh a bruise I wonder how that got there. Then I noticed it in the same place on the left boob and thought hmmm. So I pressed down on the green/yellow spots and it didn't hurt at ALL. usually if it were a bruise this bad, it would hurt! Both spots of the "jaundice" is right above the nipple like directly above the pinks of the nipple but on the right boob there's some like dark purple just looks a little discolored on the nipple under the green/yellow. WTF IS THIS??

P.s. I don't know if this matters but when I mentioned I was sick I'm pretty sure I caught it from my boyfriend and that same day he was "putting his mouth to my breats", for lack of a better term. But he didn't hurt or bruise me or bite down
