My mother and I both got our periods very young, she was 9 and I was 8, and we had very different information on it
My nana (her mother) basically skipped over the whole subject(she herself had lost her uterus in giving birth so she didn't even have them herself) but luckily mom had friends at school to warn her of it so she didnt' have a heart attack and think she was dying as per your mother, but she still was very determined to make sure i didn't have the same problem
She was incredibly thourough and scientific about it, starting from the first time i asked where babies came from at around 5
we went to the library, we checked out books, and anything she didn't exactly know herself we looked up online or asked our family doctor
It was porb difficult for her, but I really think it was the best system, to this day i'm completely comfortable coming to mom with questions about my body, or the male body, in any form, I know if she doesn't know, we both will soon
