Girls, these postings have helped me too... I've been worried that I haven't seen a darker line yet and thought i would have O'd today or tomorrow (CD13). I've had a positive OPK before using the same brand, but i've only used OPKs twice before - that cycle and this current cycle. The second line is remaining very faint and not getting progressively darker.

I think I'll just continue to check CM /temps and BD for the next 3 days or so anyway and hopefully catch the eggie... assuming I'm going to O this month.!!

I've just bought a new pack of OPKs so I think i'll do an 8pm check too.
