I am 13 years old and I have breast lumps in both breasts but they seem smaller after my period and I also have very little dimpling of breast very slight it is I can't feel it but can see it it is very little I see it when I flex my arms I also occasionally get white creamy thing in the nipple when I shower it doesn't come out it's like skin, I have told my doctor about the lump and the white and she checked it and said it's nothing to worry about your breasts are developing ,is this okay I am very scared.
