I've been using Clearblue Digital Advanced OPKs and I've missed my estrogen surge before but this month I just got 9 days of flashy smiley faces before giving up. My BBT chart looks like I ovulated, though the shift in temp isn't quite as dramatic as usual.

Clearblue's booklet says it's likely I just didn't ovulate this month OR my LH surge was too weak to be detected. What does that even mean?

Anyone have this happen and still get lucky? We baby danced according to the calendar and not the test and more than usual since the LH surge never happened.

Thanks, and baby dust to all!
