Have you been to the doctor yet? I hope so. Please keep us posted on what could be going on.
Hey there. You need to go see the doctor. You may have some internal bleeding going on somewhere in the abdomen or digestive system.
I agree with sparkle, you need to see your doctor ASAP. Please don't be embarrassed about talking with your doctor about this - it is nothing to be ashamed of - doctors have seen and heard everything, so your problem is nothing he/she never heard of before.
You must go to the doctor about a problem like this. I don't see nothing to be ashamed of? Just tell them you see blood in the toilet when you have a bowel movement.
