Good evening girls?

Good evening girls ? New mom with questions again ? We had ER 11 days ago with internal tearing. A week after delivery lochia changed - instead of blood came yellowish abundant mucous discharge. But within a day in the morning suddenly there was blood like menstruation started suddenly but stopped quickly. Today it happened again, suddenly there was blood and stopped quickly. Is this normal or should I worry? I'll see the doctor only on Saturday.
