Cognitive psychology is primarily concerned with performing laboratory experiments and conducting scientific research, but this research has led to far-reaching applications within the field of psychology.
Abnormal uterine bleeding is any bleeding from the uterus (through your vagina) other than your normal monthly period. Having extremely heavy bleeding during your period can also be considered abnormal uterine bleeding. Very heavy bleeding during a period and/or bleeding that lasts more than 7 days is called menorrhagia (say: men-oh-raj-ee-ah).
1 Vaginal bleeding is a particular concern in women older than age 50 years (or after menopause). 2  The risk of cancer increases with age. 3  Also, your vaginal walls may be dry from lack of estrogen, which may cause bleeding during or after sexual intercourse. When bleeding is not caused by your menstrual cycle, it is called abnormal or dysfunctional uterine bleeding. 2  This is the most common cause of abnormal vaginal bleeding during a woman's childbearing years. 3  Up to 10% of women may experience excessive bleeding at one time or another.
