First time using OPKs, have I missed the surge?

[IchigoMewMew]

Decided to try OPKs this month as I found some cheap strips in Poundland. Yesterdays was quite dark but still lighter than the control, todays is the lightest of all of them. Have I surged maybe this morning? Urine didn't really look more dilute today. Do I just enter them all as negative on ovia? Seems a bit pointless using them!

I don't think you've missed your surge, I don't think it's happened yet! The darkness of the second line can vary day to day,
What cd are you on and how long as your cycles usually?

Im on cd 20, cycles are usually around 33 days. Did have a random 36 day cycle after christmas, Looks like I'm having another one. Will have to go back to poundland and get another box tomorrow

So it could be any day now. Hope you get the positive soon x
