I've seen people mention a few times on this forum that OPKs do not always work for women with PCOS. Just wondering if anyone can explain why?

I can understand that you might be likely to miss things if you only check on CD9-14 or something like that but would testing every day work?

You have to have a rise in LH in order to ovulate even if you have PCOS right?

Is baseline LH too high in PCOS and causes false positives?

Confused...
