Anyone use CB advanced OPKs? I got a static smiley so assumed I ovulated a day or so later but I'm spotting very very light (have been for 5 days) with no AF but still BFNs. Does this mean I didn't ovulate? Cos I though Luteal phase doesn't change by more than a day or so, so AF should be here by now. Confused!
Anyone experienced this? Or have any idea what is going on? I'm usually very regular and since my MCs I do spot but only a couple of days then AF shows up.
