<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing vaginal discharge and uterine contractions recently. I am also having some problems during my pregnancy.  <response>: Based on your symptoms, it seems like you may have placenta previa. This is a condition where the placenta partially or completely covers the cervix, causing bleeding and contractions. It can be serious and requires close monitoring during pregnancy. I will schedule some tests for you to confirm the diagnosis.
