About the Symptom
Abnormal period describes menstrual bleeding that is abnormally heavy or irregular and unpredictable in timing. The normal length of the menstrual cycle is typically between 21 and 35 days. A normal menstrual period generally lasts up to 7 days. If the bleeding is excessively heavy (soaking through a pad or tampon) every hour, that is also considered abnormal.

Possible Causes
Generally, Abnormal period can be related to:
Abnormally heavy menstrual periods caused by blood-thinning medications, such as Aspirin and Warfarin.
This is a rare condition that can occur after uterine procedures and is diagnosed by findings bands of scar tissue (adhesions) in the uterine lining. While a dilation and curettage procedure is the most common reason patients can develop Asherman Syndrome, most patients can safely undergo such procedures without any complications. It can also occur from some genital infections such as Tuberculosis, and other less common conditions.
RPC reviewer comment - Condition would be better called "Luteal phase defect" as that is when it is clinically relevant, especially in setting of miscarriage and fertility. A condition caused by low levels of Progesterone, the female hormone that controls menstruation. An imbalance in the level of progesterone affects normal egg release (ovulation) and can cause irregular periods. This is also seen as a possible risk factor in early miscarriage and difficulty getting pregnant. Known causes include anorexia, excessive exercise, obesity, diabetes or other hormonal problems (e.g. thyroid disorders).
Related serious diseases
Sometimes, Abnormal period may be related to these serious diseases:
A condition where pregnancy occurs in any location other than the uterus. This is abnormal and most commonly occurs in the Fallopian tube, the tubes connecting the ovaries to the uterus. If the pregnancy continues to grow, it may rupture and lead to life-threatening bleeding.
