Just saying regarding timeframe, my first DC I had nothing on the test within the timeframe. Chucked the test in the bin, went away for the weekend. Had a funny turn while away, so when I came back I pulled the test out of the bin and there was a positive that looked a lot like yours. I did another test the next morning and I was pregnant. I know that you're not supposed to read the results after the time is up in case you get an evaporation line, but I don't think yours looks like an evaporation line...!
