Hey , I Believe That I Am Pregnant But I

Hey , I believe that I am pregnant but I am on my period, it was 2 days late but I had lite pink discharge those 2 days and on the 3rd day I had slight cramping with lite bleeding I am on what would be my last day of my 4 day period and I also had lite clots not much like my regular period. I woke up this morning with little to no bleed and that's not normal for me my whole period was not normal.
