Some discomfort at the time of ovulation is common. Many women with endometriosis experience significant ovulation pain, often lasting for several days. The pain is probably due to stretching and pulling of adhesions on the ovary when the ovary enlarges slightly at the time of ovulation.
Pain during vaginal examinations-Some women with endometriosis may experience pain vaginal examinations.
Bleeding-The more common bleeding problems associated with endometriosis are heavy bleeding, clotting, prolonged bleeding, premenstrual spotting, irregular cycles and irregular bleeding. A significant proportion of bleeding problems in women with endometriosis may be due to the presence of another condition, such as adenomyosis, fibroids or pelvic inflammatory disease (PID).
Heavy bleeding, with or without clotting, is a common symptom of endometriosis. Fifty-eight per cent of women surveyed believed they had experienced heavy bleeding. There is much debate amongst doctors as to just what constitutes heavy bleeding, but it would seem reasonable to assume that any woman could be said to have heavy bleeding if her menstrual loss caused anaemia or if it interfered with her normal lifestyle.
Premenstrual spotting is staining which is noticeable for at least 24 hours before the onset of menstruation. It has been reported that about 80% of women with premenstrual staining are subsequently diagnosed as having endometriosis.
