Clear Blue Ovulation predictor kit - digital? - clear blue ovulation predictor

I have two questions about the work of ovulation:

Can you prove the LH surge all the way up to 24 hours after ovulation and a positive result? The package, which states that the performance shows a maximum of 36-24 hours, so I asked if I check 24 hours before receiving a positive effect in 36 hours?

The closer your LH surge is the second line is black? As in, like maybe two days of O (ie, what the calendar says) the next time you will the OPK, the second line is even darker for today? I wonder, I am so worried that we will lose the date of my Twin?
