You should be seeing your doctor as a precaution. Never assume something and then worry about it, that is so hard on you. I would call and tell them what's going on. Hopefully, it is just hemmorhoids.
If the blood was bright red they say that is from hemmoroids, its when its a dark red colour its old blood or coming from deeper inside, that being said when you ever have blood during bowel movements you should bring it to the attention of your doctor.
