Period but pregnant?

Anyone ever had a period but been pregnant? I had really been feeling like i was pregnant, same feelings i had when pregnant with my son, then I was a few days late and started a “period” but its way different than my usual periods. Im pretty regular and my usual periods are pretty heavy. This time, very mild, not even medium amount of blood. And after 2 days it seems to be done? Could this be a random bleed and I could be pregnant or am i just having an off cycle?
