Is this real? FRER

So last month I had a chemical so I'm a little paranoid. I started using preseed and opks to figure out when I ovulate (later than expected) and bought these frer tests since everyone loves them. But I got the curved handle ones. I didn't know until later that they are infamous for indents. Now...the test line looks pretty Pink in person but anyone have something like this and it ended up to be nothing? First 2 pics taken at 3 min and last 2 pics taken at like 7 minutes.
