Hey, having different-sized breasts is perfectly normal. It's quite common for you to have different-sized breasts or nipples, especially as they develop during puberty.
Everyone's different, and no two women's breasts will look exactly the same. In fact, asymmetry where one body part, like a foot or a hand, is a slightly different size or shape from it's partner is quite common in humans.
