Help?! Update

I was four days late, took a test, negative. Today is the 5th day and I started around 12:30. But I don’t feel like I’m on my period. And so I am going to do something I always said I’d never do but I need honest opinions. This is a TMI picture, it is of blood on a pad. If you don’t want to see I would suggest looking at another post. But could this be implantation and how long should it last? Thank you in advance.

It might look like more that what it is because I got close to it with my phone. The spot is only about an inch and a half maybe, very slimy consistency when wiping. Just update
