So I’m new to tracking ovulation HELP!!

So I keep getting negatives understandable since I’m not ovulating yet. But should I be more progressing in line color or does it not matter? I’m confused on this. Should my line becoming darker a little each time or it’s just whatever? I know what it suppose to look like when positive. Any advice would help! Today it says I have 11% chance of getting pregnant but I’m not ovulating? I’m just confused help!!!
