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).
A few possibilities for vaginal bleeding include: 1  Implantation: when the fertilised egg attaches itself to the uterus wall.  Miscarriage: it is loss of pregnancy in its early stage i.e. within first twelve weeks of pregnancy.
