Dodgey opks?

Kershal

First time using this lot of OPKs i usually use the pink end ones so thinking maybe a bad batch?? Dont be fooled by the 2 that look positive as they werent that dark when in time frame will post photo of the bigger one in time frame aswel, the 5th one in was early hrs this morning CD19 came up the level just before positive by glow, ones before that are yesterday and day before wondering if iv just missed the actual surge thanks to these tests what does everyone recon??

Im on CD19 and usually get my positives CD16-17 Had a HyCoSy CD9 this month had 11 follicles in right 6 in left
