A childhood belief about periods

I read a book in the library because I was bored, about girls and puberty. I learned about how we have periods, and I learned about tampons. I thought you were only allowed to use one tampon in your entire life, and periods lasted every day. (It got reaaaaaaaaly distorted) I knew they started when you were 10-14, but I thought they lasted until the day you died. I also thought everyone wore a tampon always, and that it turned into a baby when you got married (I had a wild imagination). I never knew about sex because my parents were strict, very strage catholics, but I figured it out through another library book =). So, after we left the library, I saw a buch of women and thought "They all have tampons inside them." I finally got straightened out by my mom when I was 10. Thank God.
