My Period Is A Little Late, Only A Day. But

My period is a little late, only a day. But I've been having many pregnancy symptoms. I masturbated (penetration AND clitoral stimulation. WITH orgasm) yesterday and a considerable amount of blood (thick not runny/liquidy) came out. After that blood flushed itself out, no more came at all. What does this mean? Before I was worried I was pregnant but that blood was too much to be spotting from implantation I think. Was it period blood that I just kinda pushed out early because I masturbated too roughly? I had a tiny bit of cramping today
