Do you see a line?

I just came off bc in July with my last period August 10. My period was due sep 7 but is nowhere to be seen. I have cramps and feel like it's coming but nothing except extra discharge sorry for tmi! Maybe I ovulated late? But I took a test yesterday and today that show faint faint faint lines with a tint of blue...evap lines I thought r thin...and wouldn't my lines be getting darker every day? I would be about 4 weeks 5 days accordin to my lmp but this doesn't mKe sense!
