Abnormal uterine bleeding (AUB) is irregular bleeding from the
uterus that is longer or heavier than usual or does not occur at your regular time. For example, you may have heavy bleeding during your period or in between periods.
Bleeding during pregnancy is a different problem. If you are pregnant and have any amount of bleeding from the vagina, be sure to tell your doctor.
