Quick surge or none?

Lilly

i am currently on cycle day 18 , ive had irregular cycles. Last month I had a CP. Today I have mixed opks, when I scanned the test it gave me a negative but when I waited 5 more mins and saw all the dye clear i scanned again and it was positive that was at 10am . I tested again now at 3pm and it’s not positive and I’m just not sure if I surged yet or not
