Implantation or period

Hey all! So I’m only 19 and a college student so I’m reaaaally hoping this is my period but idk. My boyfriend and I ALWAYS use a condom so I know the chances are low that I’m pregnant, but of course I think I’m going to be that 1% that is unlucky.

I had my period from like the 4-10th of this month, and my period is always incredibly regular and I would say on the heavier side.

When I saw a tiny bit of bleeding again 2 days ago on the 25th I was like okay awesome I’m not pregnant. But then I went to log that my period had come and realized I was like 10 days early!

Now, two days into this mysterious bleeding I still barely have any blood. Like I definitely can not use a tampon and I even feel like a pad is excessive. We’re talking pantyliners.

Not only is the bleeding so little that it’s almost like I got a cut or something, the blood is like dark brown / black.

I looked up why my period might be 2 weeks early, insanely light, and black/ brown and read about implantation bleeding

What do you guys think? I’m freaking out. Two days into a “period” I should not be having like 3 drops !
