Am I or not


So went to drs yesterday they had me take a test to see if I was pregnant. So they had me pee in a cup and done test. They said they seen a dark pink like once they put my pee on stick then faded away and went negative well looked at this test this morning because they gave me it to take home and I see a very faint line but I’ve taken 3 test again already and one this morning and all 3 were negative. Suppose to start on the 3rd dr said to retake one on 4th if I don’t start. So what does everyone think ???
