Any blood in your stool during pregnancy should be reported to your doctor.
Usually blood in your stool is just a symptom of hemorrhoids. Hemorrhoids can cause pain, bleeding and itching in or around your anus. Hemorrhoids usually resolve within a few weeks after delivery. Your doctor will be able to prescribe you some medications to help you heal and provide comfort. Preparation H and Tucks Pads are both over the counter treatments that can help with the discomfort or hemorrhoids.
Don't be embarrassed to talk to your doctor about this very common problem.
