I just finished my period, but it was an irregular period- 11 days long, when mine are usually 5-6. I missed the month before, but didn't think too much about missing it, because my periods have never really been consistent. Then I was a little worried when my period was 7-8 days long, because I'd never had a period last that long. When it got to 11, I was really worried, but didn't know if it was a one time thing, and decided I'd keep track of it, and if it happened again, then I knew it was part of a definite problem. Now it's two days after my period ended, and I'm bleeding again. However, this isn't like period bleeding. This is thin and bright red. I'm really worried, and I know it's not because of taking a contraceptive or a morning after pill because I take neither. I'm not sexually active and never have been.

Any help you can offer? I would really appreciate it!
