I’m so confused..

So my period was due yesterday/today/or tomorrow, and I thought I got it today but it was just spotting and it was more rusty... very light... very very light.

And it’s barely even there now. Basically gone...

Could this be implantation cramping.

Also before you say anything, my periods are ALWAYS light/medium first day, and the blood doesn’t just go away.

So I need help lol
