<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing some symptoms lately. I have been having blood in my stool, pain during my pregnancy and I have also been struggling with infertility. What could be the problem?  <response>: Based on your symptoms, it is likely that you have a missed abortion. This is when the fetus dies, but your body doesnt recognize it right away and you continue to experience pregnancy symptoms.
