Acidity constipation. About the blood.

Yesterday i saw a drop of blood near my waste in the indian toilet of my hostel. But it was a little away from my waste. Don't know if it was mine or someone else's. I checked by sweeping all around my behind portion of any signs of blood but could not find it. I have been suffering from acid reflux( chest burn,throat burn while eating spicy food, very mild or no burn during nature call, etc) for more than two months. I have started to use kayam churn to regulate stools scince last week and it has helped. I had no pain when i saw blood. Also i don't feel pressure at all in the morning. If i don't go to the toilet on purpose, i don't feel the need to go. If i go to the toilet, it just happens really slow, although watse doesn't come out dry. Also i used digene for reducing burn for two time a day( one full bottle). But I have discontinued it now and fully rely on kayam churn. Please help. I am worried about the blood.
