Started pink bleeding yest, no cramps but a week before normal menstrual cycle due. Today heavy bleeding with clots, cramping?

A single early cycle. is usually nothing to be concerned about. Sometimes this happens due to stress or just chance. Cycles usually will normalize in the next 2-3 months. If an early, heavy period remains very heavy and does not resolve in a few days, or if there is spotting in between periods, patients should see their GYN for further instructions.
