Hi Miss J,
Sorry to be a party pooper for you but I worry that you haven't even had a positive OPK for you yet, your OPKs look positive to everyone else in colour but what everyone needs to remember is that when the LH 'surges' (see graph) that is when ovulation occurs, in my opinion you haven't had your surge yet, because the colour of your OPKs has been consistent, I would expect that when you OV you will get a line much darker than the control like the picture below.
Have a look at your opks from last time they are all consistent with no clear surge.
If your cycle is around 60 days you won't OV until about CD 46, if it is 50 days you won't OV until CD 36, if it is 40 days you won't OV until CD26.
I would definitely keep testing hun, and would not tease your self with HPTs, don't give up the OPKs I'm sure you'll get your surge soon enough, try not to stress if OV comes later so be it, I think it would be a good result for you to be able detect your surge.
Just to let you know that AC made my OV later last time and has done the same this time too.
Have you used the diggi OPK?
