Same here, I only ever got dark positives with exxy OPKs - the Oracle ones usually went to half the strength of the control.

Mejane, do you get other signs that O is approaching - like changes in cervical mucus, twinges/pain or temp drop? Might need to look for these in combo with using OPKs...ignore me if I'm telling you how to suck eggs (or should I say, pop eggs!).

If you got a positive today it should be close - back to the bedroom!
