you can wait
There are two most common reasons for blood on the tissue - hemorrhoids and fissures.
In hemorrhoids the stool is soft and dedication painless.
In fissure, the stool is hard and defecation is painful. And for this stool softeners like laxatives are helpful.
Both of these can be easily identified by a general surgeon
by clinical examination and proctoscopy.
And as your bleeding is only occasional, so you can wait and watch. If it increases then you can see a surgeon.
