Read notations like 18w4d or 18+4 as gestational age: 18 weeks and 4 days pregnant. You’ll also separate gestational age, counted from the last menstrual period, from conception or fetal age, which is usually about two weeks less.
Use what you learned in the previous lesson to solve real-world problems.
Use LMP, ultrasound dating, EDD, and EDC to understand where a due date comes from. You’ll treat 40w0d as a planning estimate, not a scheduled finish line.
Check what you understood with a short quiz.
Place a pregnancy in the first, second, or third trimester and recognize common term labels. You’ll read preterm, early term, full term, late term, and postterm as time ranges with different planning meanings.
Decode G, P, and GTPAL in a prenatal history without judging the person behind the numbers. You’ll translate entries like G2P1001 into plain language about pregnancies, births, losses, and living children.
Time contractions by frequency, duration, and pattern using the start of one contraction to the start of the next. You’ll tell the difference between “every 5 minutes,” “lasting 60 seconds,” and “getting stronger.”
Recognize common contraction words such as ctx, UCs, Braxton Hicks, irregular, regular, mild, moderate, and strong. You’ll connect each label to what the birthing person or care team is actually noticing.
Use early labor, active labor, transition, pushing, and placenta delivery as plain-language time markers. You’ll hear these as flexible stage names rather than exact promises about how fast birth will move.
Read dilation as the cervical opening measured from 0 to 10 centimeters. You’ll understand why a number like 4 cm describes one moment in labor, not a guaranteed prediction of what happens next.
Read effacement as cervical thinning, usually charted from 0% to 100%. You’ll see why someone can be very effaced but not very dilated, or dilated some while still not fully thinned.
Use station to describe how low the baby is in the pelvis, often from negative numbers to 0 to positive numbers. You’ll recognize 0 station as an important reference point and positive station as descent toward birth.
Translate cervical-check shorthand such as SVE 4/80/-1 into dilation, effacement, and station. You’ll also recognize VE or cervical exam notes as snapshots that can vary slightly between examiners.
Decode ROM, SROM, AROM, PROM, PPROM, and LOF in notes about the amniotic sac and fluid. You’ll also recognize why chart words like clear, bloody, or meconium-stained matter in birth-room communication.
Recognize FHR and FHT as shorthand for the baby’s heart rate or heart tones. You’ll read bpm, baseline, reassuring, and nonreassuring as monitoring language without needing to interpret a full fetal heart tracing.
Read common appointment shortcuts like BP, HR, T, wt, UA, GBS, Rh, WNL, neg, and pos in context. You’ll turn a dense prenatal note into plain language about vital signs, screening results, and normal findings.
