Opk advice/a good talking to please

Someone give me a shake!

Second month using cb digital opk's

I have 30/31 day cycles and last month I got a smily face on calendar day 19, unfortunately af arrived on 9th September bang on time.

This month I am still not getting even a flashing smily (cd18)

How late is too late to get a positive opk and still have a good chance of it resulting in a pregnancy?

I hope I'm worrying over nothing but this is cycle 6 after a MC back in March and cycle12 overall, starting to get pretty concerned

Anyone?? Still no smiley today

I'm not totally sure, but I think that some people have fairly short windows where they get positive results, so is it possible that if you tested once a day, the surge happened between the two tests?

Maybe google this to double check but its definitely something I've read on TTC forums before. If you think this might have happened to you, maybe use the non-digital tests where you can see the line getting stronger and stronger, and so can know when the positive result is likely to be on its way?

Thankyou, I think I'll try that next month if no joy this time round, I'm also wondering if I may have started testing too late, we have tried to keep up with every other day anyway so hopefully may have caught it regardless, thanks for the advice : )
