BBT ovulation help

Hello! I am not sure when I ovulated based on my bbt? I was not tracking with opks this month but I had excess creamy/ewcm on CD 11 so I took an opk on CD 11 and it was positive as well as on CD 12, CD 13 it was very negative. And my temp decreased and then rose so I was sure I ovulated on CD 11 or 12 but then it dipped again on CD 14. I had ovulation pain on CD 12 and was pretty sure that was it. But I am confused on the temping. When do you think I ovulated?
