I was 10 and outside playing football with my brother (I was a tom boy), ran in to use the bathroom and damn it all, it was there! I knew what it was but was pissed I didn't want it!
See my mother for some reason, just didn't talk about things in detail and it seems like puberty was definately taboo. My sister in law had to tell her that I needed a bra and that undershirts just didn't cut it anymore! So she says to me wait a minute I'll have to check you My reaction was WTF? so I went and got my undies and shoved it in her face and said SEE? Obviously that was good enough cause she gave me the big fat pad and belt combo and left me alone. My father congratulated me later that day and I was mortified .
Anyway she told me I couldn't play with the boys anymore which confused me and pissed me off even more. I hated being in the house with her. I knew all about the girl stuff from school and my sister in law, but she made me feel like they would get it if I played with them. Come to find out her fear was that I would get pregnant
Glad I don't have to deal with periods anymore.
