### Patient: Doctor, I have been experiencing vaginal discharge, involuntary urination, spotting or bleeding during pregnancy and uterine contractions, what could be the problem?
### Doctor: Based on your symptoms, it seems that you might have placenta previa, a condition where the placenta is located low in your uterus, partially or completely blocking the cervix. This can cause bleeding and contractions, and may require bed rest and even premature delivery to avoid complications for both you and your baby.
