No, green stool is not typically a sign of pregnancy. Changes in stool color can be related to diet, medications, or specific health conditions. While some women experience changes in bowel movements during pregnancy due to hormonal shifts, it's essential to also consider other symptoms and signs. If you're experiencing other pregnancy symptoms or have missed a period, it may be beneficial to take a pregnancy test. Remember, if you have any concerns about abnormal symptoms or health issues, it's critical to consult a healthcare professional.
