Hi, honey, I hope you mean you have been wiping front to back. Always from the vagina (which is clean) towards the anus (which is bacterial). Never the other way around.
As far as the appearance, it's likely to be normal and just look unusual to you, unless you have had some trauma earlier in that area. Your ob/gyn doctor (gynecologist) will be able to reassure you when you have your first gyn exam. Given that you are worried, you might ask your mom to set you up with a gyn when you are 15. It's a tiny bit early, I think my first pelvic exam was when I was 16, but won't hurt anything, and might relieve your mind a lot.
