First ever positive opk ? Did I miss my surge ?

J

Got home from work last night and took an opk yesterday was CD12 . I took the test on the toilet while the shower was running I'm not sure if the steam made my test evap but I got a BLAZING positive on an opk it's never been darker than the control line I didn't get to BD last night because DF was stressed over a situation that happened earlier (very minor car accident , guy trying to press charges When HE HIT US) anyways . I woke up and took an opk this morning and it's blanttently negitive.. did I miss my surge ? Please help anyone !!
