Wtf!?!? I’m so confused

Ok… so a day before af came i was getting a faint line. Like super faint. I just got off of af as of yesterday, it was 4 days long. It was clearly af.. so i thought i was out. I began to take ovulation test today and was shocked that it was so dark right after af ended. Now with my son .. i only spotted the entire pregnancy. No heavy bleeding. Just for fun .. i took another ovulation test and took a pregnancy test to see if something was wrong with this box of test because i just got them from Amazon. Y’all .. these are all test i took just now.
