So... it's CD 24 for me. Thought I ovulated around day 14 going by CM (not charting) but I've had EWCM the last 2 days, and I have a regular cycle of 29-32 days (is that long?) I've used OPK from CD10-CD20 with no positive result and this is what I just got, on CD24. This is the darkest line I've seen so far on an OPK - is this a positive or still too faint??? First cycle TTC so I'm basically clueless..
