Need some help! Please

Soo I had a missed period and I’m pretty sure that I just experienced implantation bleeding… and another thing that I experienced is green poop (sorry TMI) and I thought that’s was odd and then I did research on the implantation bleeding and I saw that green poop is a sign of pregnancy… so do you think I’m pregnant?

I’ve taken test before the bleeding and they came back negative. I’ve taken one yesterday when I realized what I went through 4 or 5 days ago was implantation bleeding and it also came back negative…
