Breast cancer??? Early signs??

Maria

So I’m 18. And I didn’t have my period for over 100 days, and I recently started birth control to get back on my regular cycle. But it seems like my one boob got a weird discoloration around the nipple. Specifically a big of a darker or lighter shade just below the nipple (like it had grown or something). Is this normal? I did a breast exam on myself, and I didn’t feel any lumps or something hard. But maybe I missed something? I’ve been trying to get in contact with my doctor but they don’t answer Sundays (go figures).

I’ve been freaking out because I can’t tell and I’m so scared. I had my mom look at it and she said it looked normal, but it just doesn’t feel right. I don’t know how to explain it.

Update:there is a solid type thing at the top of my boob (so a bit above the nipple if that makes sense) it doesn’t hurt, but it does feel kinda hard and my other boob doesn’t have it.
