 L (Living): number of currently living children.
o Due Date: from the month of their last period add nine months, then add seven days to the first day of their last period.
o Nägele’s Rule: most common method of determining the EDB, which uses 280 days as the mean length of pregnancy. To
use this method, begin with the first day of LMP, subtract 3 months and add 7 days. For
 Presumptive Changes
Subjective symptoms experienced by the woman. Doesn’t confirm pregnancy.
o Morning sickness
o Excessive fatigue

 Contractions of TRUE LABOR produce progressive DILATION and EFFACEMENT of the Cervix, occur regularly with increase in
frequency, duration and intensity.
 The discomfort of true labor contractions usually starts in the back and radiates around the abdomen. pain is not relieved by
ambulation (walking may actually intensify pain)
 The contractions of FALSE LABOR DO NOT produce cervical effacement and dilation. They are irregular, and do not increase in
frequency, duration, and intensity, perceived as a hardening or “balling up” without discomfort, or discomfort may occur in the
lower abd. or groin.
 Discomfort may be relieved by ambulation, change position.
 S/S of impending labor
 Lightening (when the fetus begins to settle into the pelvic inlet (engagement).
 Braxton Hicks Contractions
