what shape do breasts start developing?

Okay so when breasts first start developing, they usually begin as a small, raised bump under your nipple. It's kind of like a tiny mound, and sometimes it can feel a little tender or sore. This stage is called a "breast bud."

After that, your breasts will gradually get fuller and rounder. They won't just pop out fully formed, it's a super slow process. One might even grow faster than the other for a while, which is totally normal. They keep changing shape and size throughout your teen years and even beyond, because hormones are always doing their thing!

Everybody is different, so your breasts might not look exactly like your friends' or what you see on TV, and that's completely fine. There's no one "right" shape for developing breasts.
