My daughter is 8 years old. She is a thin, little girl, showing absolutely no visible signs of puberty at all. Tonight, she took me aside and told me that she had bled a couple of times today. I tried to hide my shock, but I don't know how well I succeeded. I didn't start menstruating until I was 14, nearly double my daughter's age. Is it possible it could be something else? I cannot imagine that my little girl would start her period so young, and with no signs of puberty coming beforehand. Any thoughts?
