Is this a positive opk?

Hi. Would you say this was positive? They just arrived in the post today so I did one straight away!

I would say probably but the picture is not very clear. Try again in a couple of hours. Unfortunately you can get a surge without ov and find it drops again. So if it's early on in your cycle, it could be that. I seem to get one on cd4ish and BD just in case but get endothermic surge CD13 which ties in the bbt temp rise.

Endothermic was autocorrect for a second!

Thanks! I think this is around when I ov. Today is cd 12 of a typically 23 day cycle.

If it's still like that this afternoon/evening is it likely to be the ov surge?

I think it's nearly there, do another. I would be surprised if it's not positive today/tomorrow.

It was slightly fainter yesterday when I did one later in the day. Does that mean the surge is on the way out? I'll do one again in a couple of hours.
