Red discharge should always be alarming; it's a reason to urgently call an ambulance and go to the maternity hospital without a minute's hesitation. I hope everything is okay with you? Please let me know.
At 39 weeks of pregnancy, bright red discharge can be a sign of labor beginning, especially if accompanied by contractions and cervical dilation. However, such discharge can also be caused by other reasons, such as an infection, cervical injury, or bleeding. In any case, it is important to consult a doctor to assess the condition and prescribe the necessary treatment.
