Evaps or pregnant

We all know that these posts tick people off am I pregnant or not right when the line is clearly there! But sometimes it's not so simple. Took these tests starting on the 9th up until now all I thought looked like they had small faint lines but hey who don't get line eyes!! Right! Any ways then lines clearly got darker after the allotted time! I'm no doctor so I don't know! Just take a look please and let me know your options? Second to last picture is the faintest one.
