<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing some unusual symptoms lately, including spotting or bleeding during my pregnancy and blood in my stool. What could be causing this?  <response>: Based on your symptoms, it is possible that you have subacute thyroiditis, which can cause abnormal uterine bleeding and gastrointestinal bleeding. I recommend further testing and evaluation to confirm this diagnosis.
