What do you see? Anyone else see the vfl?

The first is original and last 3 are Tweaked. I need hope :( I took 6 tests and they ALL looked exactly like this an they were taken fmu. My last period was 3 days late and only lasted 10hours. But I'm thinking it may have been implantation bleeding. I have a two year old and I had implantation bleeding for 3 days when I was pregnant with him. It's been 6 days since that happened. And I have tested everyday since the bleeding. The picture was taken yesterday 3minutes after I took the test, sat on a flat surface... I did it all correctly. I took so many because I was hoping the line would get darker but nope... It's a first response rapid results test and yes I used the same test everyday. Praying for a BFP!
