Help?

I’ve gotten two extremely faint positives i thought and had so many symptoms of pregnancy but I thought I started my period today (three days late) but the blood was brown and I put in a pad and two hours later I’m still cramping a lil but there’s like no blood in it. What’s happening???? Weird implantation? Weird period? I’m keeping the pad in but i want to hear other thoughts/opinions. When I wiped there was a little more red blood but when I wiped again there was almost nothing.
