Morning chick.
You are far too young to be sure yet. It's natural to be attracted to both sexes at your age, you'd be surprised how many are. You are also too young to be going through puberty, although it's not impossible. You will have many friends of both sexes and they will come and go, that's the way of it. It goes on throughout life. Some friends will be good friends and will always be so, some will be friends for a short while and move on, as will you in their lives. Enjoy the company of both sexes and be assured that you are normal. Enjoy your childhood and what will be will be.
