best person to ask will be your GP. Make an appointment asap

I agree, this could be very serious. I know someone who ignored it for 6 months and ended up very seriously ill

the colour of the blood is important, bright red blood is less serious, it could be an anal tear, maybe you become constipated when stressed? darker coloured blood that is in the stool should be looked at seriously

what ever you do, go and see your doctor, just to put your mind at rest

I can only echo what everyone else has said.
See your GP ASAP.
