ovulation test question

Hi girls!
I need your help!
I know it's not a positive opk but I need to know, can you have a line like that at any time of your cycle? Or only when you're close to ovulation? I have irregulars periods and I just started taking Vitex... This is the darkest line I ever had.
I know it must be obvious for some of you but I'm new with all that. :)
Thank you ladies :)
