Pregnancy test help!

Hello! So I’ve read so much about blue dye tests and Evap lines it’s given me a headache lol….. I’ve been testing these past 4 days…. On Saturday i tested at 10am and got a faintish blue line within the time frame on instructions and that line got dark as time passed…. I took a 2nd that same day at 3:30pm and same thing happened. Got a very faint line within time allowed and it got a bit dark but not as much as the 1st…. The next 3 days it’s only been faint lines and not any darker…. I read this https://www.mumsnet.com/Talk/conception/2484961-The-myth-of-Evap-lines#prettyPhoto …. And it kept me thinking…. I’ve posted the first 2 i took… opinions? Positive or Evaps?
