The hymen may be broken without any immoral action taking place

I am a 17 year old girl, and I have a question: I remember that when I was ten years old, before I reached puberty, there was a little bit of bleeding, but I did not know what that meant. I thought that it was menstrual blood, but now I think that the cause was a rupture of the hymen because the water that I was using to clean myself after using the toilet came out very strongly. .. Perhaps that was the reason. I want to know the explanation of that, because praise be to Allaah I am chaste and I pray regularly, and I am not saying that to conceal something that I did wrong.
