Summary
A detailed description of the menstrual cycle is not within the scope of this chapter. An understanding of dating early pregnancy from the last menstrual period (LMP) dates and adjusting this for cycle length is, however, essential in the management of early pregnancy problems. The first day of the LMP is the first day of bleeding and represents the shedding of the endometrium associated with the drop in ovarian hormone production in the absence of conception.
