Positive OPK with a line not as thick??

[LMmamax2]

So I've been testing with OPKs along with monitoring BBT and CM, and I got a faint line in the evening yesterday. This afternoon I got a line that looked almost a dark but a little spotty, the whole line wasn't the same color or completely there almost. This evening I took another one and it looks as dark as the test line on one side but the darkness doesn't go through the entire thickness of the line. It looks like it's the same color as the test line on one side vertically on the left and then a little fainter on the right. I'm due to O anytime in the next couple of days. Should I count this as a positive or keep testing?

Sounds good to me. I usually use ICs for checking through the day...then when it starts to look positive I confirm with a digi xx
