I have an 11 year old daughter and she says that when she feels her right breast , she can feel a lump underneath her nipple that is sore but not in her left breast.
Also, she says that in her knickers she see's brown smudges but doesnt think that she has started her periods. She is a very mature 11 year old and would never make that up so i just need to know whether the lump in her right ( a bit developing ) breast is something i should worry about and whether she is actually starting periods
P.S She has started puberty .
