Currently on CD 53, thought I ovulated on CD 12 from +opk, EWCM, followed by -opks the days after. Now starting CD 24 I've had very dark positive opks up to and including todays. I got tested for PCOS with blood test and ultrasound and everything came back normal. Took my millionth HPT last Friday obvious BFN. Anyone had any experiences like this or have any idea what could be going on? I've used two different batches of Wondfos and I had negatives from CD 13 to 24 so I don't think it's the test. So weird!!
