I Have Never Inserted Anything Into My Vagina, I Never

I have never inserted anything into my vagina, I never inserted fingers or toys or anything.. However, I rub it from the out side with pressure. The good feeling only lasts for seconds. BUT once, I woke up the next day (after rubbing the previous might) and I had little blood in the vaginal liquid in my pants. It was pinkish.. But I didn't feel any pain at all. I am worried that I have broken my hymen, as it is VERY important in my culture to have your hymen intact before marriage!! Plz help!! I want to know if the blood was due to breaking my hymen!!
