OPK/Ov question please help!

[mzswizz]

ok last cycle i o'd on cd19 because my first pos was cd18. So this cycle i have decided to test at cd18 again and to my surprise it was not a positive but a light negative. And i took another one today cd19 and its even lighter than the cd18 opk. My question is does that mean i o'd on cd17 or cd18?

Here are the pics:

cd18 -

cd19-

By the way, the control line is the line on the left and the test line is the line on the right.

Dont think you could really be sure. My instinct would be 18th as the line is quite dark, or late on the 17th if not. No earlier than that.

Thanks for your help. I was thinking on cd17 i was catching the very end of the surge and on cd18 the surge was pretty much gone. So since it was already getting lighter on cd17 does that mean i was o'ing cd17 and was just catching the last of it? Sorry for the questions

It's so hard to tell when you didn't test earlier and have something to compare it to... If you have somewhat regular cycles (due for AF in 2 weeks) and don't get a positive in the next couple days, I'd say assume CD18 was the end of your surge. Unless you temp too, you really won't know til you get a BFP or AF. Hoping you get your bfp though.

Thanks L.E. and my cycles have a LP of 14 days so I will just start testing on the 13th until AF due date and see what happens.
