Fossils are not only the actual remains of organisms, such as teeth, bones, shell, and leaves (body fossils), but also the results of their activity, such as burrows and foot prints (trace fossils), and organic compounds they produce by biochemical processes (chemical fossils).
There are two types of dysmenorrhoea: primary dysmenorrhoea and secondary dysmenorrhoea. Primary dysmenorrhoea is another name for common menstrual cramps. Cramps usually begin one to two years after a woman starts getting her period. Pain usually is felt in the lower abdomen or back and can be mild to severe. Common menstrual cramps often start shortly before or at the onset of the period and last for one to three days. They usually become less painful as a woman ages and may stop entirely after the woman has a baby. Secondary dysmenorrhoea is pain caused by a disorder in the woman's reproductive organs.
Some women's breasts hurt around the time they are about to have their period, while others feel pain throughout the cycle. Older women may experience breast pain after menopause and it may be described as a localized pain. It can also be a sharp burning pain, although some feel a certain tightness or tenderness.any young women experience breast pain within two weeks before their menstrual period and this may or may not occur with every cycle until they undergo menopause. However, this type of cyclic breast pain usually wanes after their period.
