Um... Yeah :d After pushing stool out (oddest name for sh!t ever) there's a tiny bit of blood and a bit of a pinkish-red tint on the paper Doctor visit y/n?
Most common cause, particularly if, you had to strain at all to eliminate, is a minor hemorrhoid, internal or external that's bleeding a little. Lots of people have them and they aren't a big deal. My understanding is that generally, when you see red blood, that's the most common cause. If so, then it should clear up by itself in several days. If it's still doing that after 3 or 4 days, if there's a lot of blood, or if the blood is much darker in color, then it would be advisable to make an appointment with your doctor.
As said above, if it's darker in colour then see a doctor. Till then it sounds like a hemorrhoid. Eat plenty of fiber and don't strain over the next week or 2. All the best.
