Did I miss surge ?

[Missy8484]

Need advice , I gave up my opk, but just dug them out, the top one is from Sunday and bottom one today...the top one is CD 14 and today's CD 15, now I think I just caught the ending of my surge , as Sundays is positive but the dark test line is receding back and today's is negative they look the same but it's faded and not as strong as Sundays, my past tests are usually positive on a CD 11/12 then ovulation on day 13, so do u think my strongest surge would've been the Saturday??? ,and I've caught the tale end I need advice as I've just had unprocted sex on CD 13/14 if I didn't test i wouldn't have known but I looked at my app and saw I was fertile ...i have some ovulation pains wondering if I'm ovulating today and what the chances of sperm surving 1 to days are ? Am I being naive this was unprotected sex with a male friend unplanned.....my app is saying fertile until today.... am I being silly if I do nothing , wat are the chances of pregnancy if I do nothing, I haven't got long to decided if I should get the morning after pill, torn coz I want a baby but not sure if this is the right way to do it, posted pic of test
