Help with opk please?? Is the line getting darker?

Hi ladies, I’ve been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> this month and am supposed to ovulate today. The past 4 days opks have been negative, barely no line.

The top test is yesterday and the bottom today. Is the line getting darker? I’m supposed to ovulate today, will this mean I will in a few days?
