Help please

So I diddnt come on my period yesterday and I thought I had a few symptoms so I took a test yesterday with my first morning wee and I’m not sure if you can see a line but I showed some of my friends and they did the black and whit imagine and stuff can you see it? Then I have just took another one but it seems to be really faint or none exsistant, the photo at the end is both off them together the one I took yesterday morning is on the top, could yesterday’s be like that Becuase I took it in the morning and your hormones change through the day? Or is there no lines at all on these tests?
