Any advice- might be gross/tmi

My period is 2 days late but today I thought it started. I went to the bathroom and when i wiped there was light pink blood like my period was starting so I put in my diva cup. When I emptied my cup there were just a couple drops of darker almost brown blood, as if I was spotting like the last day of my period or something. Any thoughts? Am I pregnant? Is this implementation bleeding or am I jumping the gun?
