Am I pregnant??

I am super confused and wondering if anyone has experienced this same thing... my period is due in 2 days, and I have taken 5 pregnancy tests all positive with faint lines and a digital that said ‘Yes’. I went to the doctors today to confirm and took a pee test and the dr came back and said negative and could have been chemical pregnancy. He ordered a blood test to confirm, but I won’t take that until Tuesday. I came home and just took another test which is below and it looks very positive to me. I just don’t understand why all the pregnancy tests I have taken are positive, but the doctors was negative. Has anyone else experienced this? Thanks!!
