Not sure what to think evap???

Georgie
So I orderd some ovulation tests along with a few pregnancy test strips just to stock up, thought I would take an ovulation test this morning as my periods have been all over the place recently I've had two periods in the last 4 weeks, the test showed I was ovulating so I thought I would do another one along with a pregnancy test .. And I'm not sure what I see on the pregnancy test is it a evap?? Please can anyone else help me.. The top two tests are ovulation the bottom is pregnancy ​what do you guys think?? I've heard these tests can give false readings.
