Patterns
While the normal menstrual cycle in the human typically lasts 4 weeks (28 days, range 21-35 days) and consists of a follicular phase, ovulation, and a luteal phase, followed by either menstruation or pregnancy, the anovulatory cycle has cycle lengths of varying degrees. In many circumstances, menstrual intervals are prolonged exceeding 35 days leading to oligomenorrhea (cycle >35- 180 days interval), or even longer, amenorrhea. In other cases, menstruation may be fairly regular (eumenorrhea), or more frequent (intervals < 21 days), or there may be a loss of menstrual pattern (menorrhagia, dysfunctional uterine bleeding).

Famous quotes containing the word patterns:
“For the man who should loose me is dead,
Fighting with the Duke in Flanders,
In a pattern called a war.
Christ! What are patterns for?”
—Amy Lowell (1874–1925)
“Persons grouped around a fire or candle for warmth or light are less able to pursue independent thoughts, or even tasks, than people supplied with electric light. In the same way, the social and educational patterns latent in automation are those of self- employment and artistic autonomy.”
—Marshall McLuhan (1911–1980)
“I’ve begun to appreciate the generational patterns that ripple out from our lives like stones dropped in water, pulsing outward even after we are gone. Although we have but one childhood, we relive it first through our children’s and then our grandchildren’s eyes.”
—Anne Cassidy (20th century)
