They've all been negative (in my opinion). There were a couple that OH thought were positive (evening of Feb 8th and morning of Feb 9th), but I wasn't convinced as I don't think the lines are as dark as the control line. (I have pics).
But my Temp still hasn't spiked so I guess they can't have been positive anyway.
This has happened a couple of times before in the last 8 months and I ended up going to the doctor as I'd had a couple of episodes of mid-cycle spotting too. PCOS was then diagnosed (in December), proving I don't ovulate properly/regularly.
That's why I started taking Vitex in January, this is the first time it's happened again since PCOS was diagnosed so it's really disheartening.
