Can snot like mucus be sign of labor?

Yes, thick, mucus-like discharge can be a sign of labor, particularly if it resembles the "bloody show," which is a mix of cervical mucus and blood that occurs as the cervix begins to dilate. This discharge can indicate that the body is preparing for labor. However, it can also occur weeks before labor starts, so it's essential to consider other signs of labor and consult a healthcare provider for guidance.
