Did I have an LH surge????

Cheryl
I'm very confused... I have been peeing on ovulation sticks 2-4 tines a day since I finished my period. Things started to look promising on the 9th and 10th May but not dark enough yet but today the lines has faced considerably. I had sex today around 4pm so would that have worked if I did happen to ovulate? Pics of tests will follow. Help please!
