Blood when i whip but not in the tiolet

Okay ladies I need you're opinions, I started my period on the 14 and it ended on the 17. Well I think it was a period I'm not for sure because this is the first time this has happened to me. The only time I saw blood is when I would whipp it didn't show up in the toilet, but it did show up on the pad. I don't normally have crappys but this time I did. I don't know what this means. Had anyone else going threw this.
