I should be 6w 6days i went for a scan on thursday and they found a heart beat and they also said there was some blood outside the sack

I have woken up early this morning lossing blood but no cramping at all, do you think i am just lossing the blood they saw out side the sack or could i be having a miscarriage with no pain? X
