Ovulation. Charting.?

Question

I'm a little confused about my chart this month:

I'm not always the best about remembering to check my BBT before I get up but usually there is some pattern.

I took an ovulation test (clear blue) on Saturday (day 13) and it came out positive. I'm still have trouble seeing about which day I ovulated...I assumed Sunday. I couldn't wait any longer so I took a home preg. test(clear blue digital) and it was negative this morning. Any suggestions
