False positive target brand ??

I took a pregnancy test this afternoon around 2 or 3 because I’ve been feeling off lately and it came back with a faint but obvious positive. I took another around 5 this evening and hardly anything showed up?! They were both blue but the second one was almost none existent? Could the first one just be false? I don’t know what to do 😩

Edit: this aren’t the best pics but they are both blue in person and slightly darker (my lighting is terrible haha) but what do y’all think?
