For Teenagers That Love To Write Forum A Little Help Please...

I'm writing my first ever serious book where my character is telling the story or I am the character lol but I'm not sure how to introduce my character into the plot. Can I go through the first chapter without even mentioning her name, then kind of slip it in somewhere. Can I introduce her when she meets up with another character in chapter one who is vitally important to the plot?

I'm not sure what to do. Please help.
