What in the holy areola ???

Okay so this is 3rd living baby. 3rd time breastfeeding. Ive been breastfeeding for over a year && im pretty sure that could be the cause. But idk. So my left areola is so much larger and so much lighter than the other one. It doesnt look deadly its just very new and very different. Just wondering if any breastfeeding mothers have this happen ? Or anyone have it during pregnancy ? Anyone have it happen period lol.
