Hello.
I'll begin with the fact that I am fourteen years old. Like the topic says, my breasts are hurting. Well, it isn't much of pain but it's pretty sore on the sides and the 'top' of the breasts.
Both breasts are hurting, both are equally sore.
I never sleep on my front, so I don't think my breasts are sore from the pressure.
My period is due on the 26th, so it may just be hormones.
