Positive Ovulation Test @ 11 DPO

Sarah
I am 11 DPO, and have been having cramps, gas, and a back ache for about a week. I know I ovulated around 1/18. Starting today, I have had pulling on my right side, and breast pain. I decided to take an ovulation test. It was extremely positive. Like the test line was way darker than the control. Why would it be positive again?
