o First trimester: 0-12 weeks
o Second trimester: 13-28 weeks
o Third trimester: 29-40 weeks
The average pregnancy lasts 280 days from the first day of the last menstrual period (266
days from time of ovulation), 9 calendar months, 40 weeks
Nagele’s Rule pg. 404 is to count back 3 months from the first day of the last menstrual
period and add 7 days

Phases of Pregnancy
Antepartum: the time between conception and the onset of labor
Intrapartum: period from the onset of true labor until the birth of the baby and placenta
Postpartum: time from birth until the women’s body returns to prepregnant state. Usually
about 6 weeks
True labor pg. 457: contractions occurring at regular intervals that increase in frequency,
duration, and intensity. True labor contractions bring about progressive cervical dilation and
effacement
False labor: occurs in the latter weeks of some pregnancies in which irregular uterine
contractions are felt, but the cervix is not affected
