Hey! I've got a question about opks, but first a little background. My husband and I will be celebrating our 2nd anniversary Monday the 28th. We have been not trying not preventing (ntnp) for at least the last year. So needless to say it's been very frustrating for me every month.

Now af showed up this morning :-( and I've been looking at opks because I'm only going off my apps tracking and cm (which is not always helpful).

My question is what kinds do you ladies use and why would you recommend them? Lines or digital? What brand? Please give me some recommendations ladies, thanks!
