Has anyone else had this?

I am 8 days past my missed period. I have been taking tests daily. My first positive was 4 days after my missed period. The line on preg test have been very very faint. Today it was still faint. The purple dye test barely show up. The line is slightly darker on pink dye test but still faint. Has this indicated anything bad for anyone? Has anyone had this happen and had a legit pregnancy? I am excited but also nervous this means something isn’t right. (I am going to see a dr in 2 weeks)
