Third Trimester: Are You Ready For Labor And Birth?

For pregnant women, the thought of giving birth is both exciting and slightly scary. There are the obvious concerns about complications and pain, but not knowing what to expect certainly exacerbates any fear first-time mothers have.

In this overview, we talk you through the signs of labor, the delivery itself, and the aftermath. 

Before Labor And Birth

Couples who are going to have a baby will find out what their estimated due date is early on in the pregnancy. Everyone “knows” that human pregnancies last about nine months and many are aware that the average pregnancy lasts about 40 weeks, but the due date is actually calculated by adding 280 days to the day on which the woman's last menstrual period started. Once a woman reaches 38 weeks gestation, the pregnancy is considered full term. If labor starts before that time, the baby will be born prematurely.

But what are the signs that a woman is about to go into labor? How can she differentiate between the Braxton Hicks or “practice” contractions she has been having for a good while, and the real thing? 

Braxton Hicks contractions can start being a little painful toward the end of pregnancy, but they do not follow a predictable pattern and will subside when the woman changes positions. Labor contractions first appear as short waves that do not feel unlike menstrual cramps. They will gradually lengthen, come closer together, and become more painful. Expectant moms who recognize labor contractions should head to hospital or call their midwife.

Other signs of impending labor include losing the mucus plug, which is literally a thick plug of mucus that sealed the cervix shut during pregnancy. It protected the baby from infections, but when it is expelled, labor will often start within 24 hours. A rupture of membranes (the “waters breaking”) is an even more dramatic sign that the baby is on its way.

Labor And Birth

During labor and birth, the medical team will monitor mother and baby in various ways to ensure their well-being and spot problems early on. Electronic fetal monitoring may be constant or intermittent, depending on the risk level of the pregnancy. The mother's blood pressure may be monitored, and the mother's cervix will be checked.

During pregnancy, the cervix will have gradually begun to soften, shorten and open to prepare for the baby's birth. If this happens to soon, it indicates a risk of premature labor, but during labor the cervix indicates how labor is progressing.

In some cases, labor won't progress (termed “failure to progress” or a “stalled labor”), and a cesarean section may become necessary if artificial augmentation of labor does not speed it up. C-sections may also be carried out because of fetal positions such as breech or transverse (side-ways), a twin pregnancy, a maternal infection, a previous cesarean, or other medical reasons. Some mothers opt for an elective cesarean section. The risk of maternal death due to a c-section is tiny, but real at six in 100,000 births.
