Hi all, quick question... So I am day 75 into my cycle. Starting to give up then for various reasons tmi alert ..v.soft cervix, twinges general 'what the hell sense' I decide to try an opk this afternoon. Came out with quite a line. Now I know that as it wasn't as strong as the control that it is not a positive, but here is my question...does this happen and then get darker as nearer to the big o? Or is there always a bit of a line... I should mention, they are cheap tests....
