helppp!!

so the past three days my cousin has taken all different types of tests, all have faint positives in 3-4 minutes she also took an ovulation test it it isn’t fully positive but there’s a line there. she went to the dr. today and they gave her a pregnancy test to take and it was negative, we showed her the tests she’s taken and the dr. said “all of those test are negative” so they took her blood and the results should be back in a few days. I just don’t understand why she would say they’re negative when there’s a faint line on all of them in the time frame *first picture is ovulation test and second picture is the frer she took both of those ten minutes ago but the pictures of them are at five minute mark*

these are all seperate tests as well
