I'm wondering now if AF has turned up. I thought it might have been ovulation spotting but it slightly more than just spotting. I got a +ve OPK on cd36 and had scan on cd43. Sonographer said it looks as though I've ov'd but couldnt be sure. So assuming this opk was correct and Af has arrived (very very subtly) that would give me a luteal phase of 23/24 days! is this possible? I do have PCOS btw. And am completely aware that OPKs are not a good idea. So now assuming this OPK was wrong and sonographer was wrong then could I be ov'ing very late? I'm now CD60
