Leaking boobs, my 13 yr old daughters boobs are leaking a clear water substance also hurting her but she is not pregnant. Thank you

This is usually caused by pregnancy, but can also be caused by hormones. She is at the age when her breast size is beginning to increase, this is caused by a rise in hormones that can cause this clear fluid that can leak.

To be certain though, it is best you take her to the doctor for a proper diagnosis.
