So earlier today around 1pm I did my OPK, and the line was not as dark as the control line, but definitely not faint either (earlier in the cycle there was no line at all, or so faint you had to squint to see it). I thought for sure my surge was coming and I'd test again later and see a darker line. So, just a few minutes ago, I did another one, and the line is so faint you can barely see it!

This is my first cycle using OPK's and they're driving me nuts
So...was the first one a fluke? Or did my surge happen and I missed it? How fast does this happen, is it something I could miss in just a few hours? I want to put positive in my chart, but I'm just not sure
