Still kind of new to ovulation tests..

Does the second line show up no matter what or does it only show up as you get closer to your LH surge? I know when you are ovulating the line is dark or darker than the control line but what about before? Does it mean nothing or does it mean you are in your fertile week?

I’m still a couple of days out from my fertile week but for the past few months I’ve either ovulated a few days earlier or a few days later than the predicted date
