Reaching a full-term pregnancy is believed to help in the maximum development of the baby, and you may want to reach full-term, for your baby’s good health and healthy delivery. But most moms-to-be have different ideas about full-term pregnancy. Now if you’ve just got the ‘good news’, the information about full-term pregnancy in this article will help you understand everything you need to know about full-term pregnancy!

What is Full-Term Pregnancy?

A full-term pregnancy is one that completes 39 weeks. During medical emergencies, doctors may opt for early delivery, but delivering the baby in the 39the week of pregnancy is the best possible scenario under normal circumstances. Until a few years ago, a pregnancy completing 37 weeks was considered to be full-term, however, according to the statement by the American College of Obstetricians and Gynecologists (ACOG) in 2013, it was concluded that pregnancy is full-term at 39 weeks.

What Are the Different Pregnancy Terms?

Depending upon the duration the gestation period lasts for, pregnancy terms can be categorised as follows:

• Early-term

This is referred to as pregnancy age and is between 37 weeks 0 days and 38 weeks 6 days.

• Full-term

A pregnancy that lasts between 39 weeks 0 days and 40 weeks 6 days is considered to be a full-term pregnancy.

• Late-term

When the gestation period lasts between 41 weeks 0 days and 41 weeks 6 days, it is considered as late-term.

• Post-term

A pregnancy that lasts 42 weeks 0 days and beyond is termed to be post-term.

At 39 weeks, the baby will have attained normal growth making it a full-term pregnancy and is the optimal time for delivery.

Why Is 39 Weeks Considered Full-term?

As per research, babies born at 39-40 weeks were less susceptible to health issues than those born at 37 weeks. Babies born at 39 weeks have more time for their brain, liver, and lungs to develop than babies who are born at 37 or 38 weeks. These babies may also have a healthy weight, fewer vision problems, and may also be able to suck and swallow better at birth.

Baby’s Development at Full-Term Pregnancy

Starting from 37 weeks, a baby’s different body parts start maturing to achieve full growth. The digestive system starts forming meconium, which later transforms into baby’s first excreta after birth.

The baby’s head starts moving towards the pelvis of the mother. In medical terms, this position is known, as ‘engaged’. In certain cases, this position occurs only after labour. Up until this time, the baby is covered in lanugo (the first few hair produced by baby’s hair follicles), but at 39 weeks, or when pregnancy reaches its full term, it goes away. Yet, there are some babies who may have patches of it even after birth. The baby’s genitals also look swollen at birth and this happens due to the hormonal level changes in the mother’s body, but they soon attain its normal size.

Changes in the Mother’s Body at 39 to 40 Weeks

When the pregnancy reaches its 39^th week, the uterus muscles begin to tense and the mom-to-be may also experience false indications of labour. This condition is known as Braxton Hicks. Whatever changes you feel, inform your doctor about the same.

The baby starts moving into the pelvic area leading to discomfort in the region and you may also experience sharp stab like sensation in the region when this occurs. This poking feeling is usually a result of the baby turning its head.

Vaginal discharge in the form of white mucus sometimes with a tinge of blood also occurs at this stage.

Is it Ok if the Baby Stays in the Womb for as Long as Possible?

If the baby is in the womb past the full-term, the term may get extended by a week, but the baby should not remain in the womb for longer than that. Babies should be born at full-term, anything before or after is certainly not healthy and in some cases, it can affect the baby’s health.

What if I Have an Early Term Pregnancy?

An early term pregnancy is when the baby is born at 37 weeks, before reaching the full-term. Research has shown that babies born at an early term could be physiologically immature. Early term babies may also be at the risk of many diseases, especially ones related to immunity, such as wheezing, asthma and more. They may also be at the risk of developing gastrointestinal disorders.

Is it Risky to Have a Late-Term Pregnancy?

Having a late-term pregnancy can be risky for both the infant and the mother. In babies, it could lead to breathing problems, sudden halt in growth, slow heart rate and more. The amniotic fluid starts decreasing which means it could be even fatal for the baby. Stillbirth too can occur in some cases. Also, since the baby tends to be heavy during late-term, there could be complications in the delivery process as well, and it could lead to a C-section.

What Are the Risks Associated With a Post-term Pregnancy?

In post-term pregnancy, the baby is not delivered until after 42 weeks, that is, three weeks after the medically accepted full-term (i.e., 39 weeks). A post-term pregnancy can mean health complications for both mother and the baby.

Some risks associated with post-term pregnancy are explained below.

• The Baby Might Be Overweight: Post-term babies tend to be over 8 pounds. Medically this condition is known as fetal macrosomia which can lead to obesity and diabetes in the future. Overweight babies are also a health risk to the mother as the body size could cause uterine ruptures during delivery and also result in lacerations in the genital tract. This will also mean heavy bleeding.
• Less Availability of Oxygen to the Baby: By the time pregnancy reaches its full-term, the placenta that delivers oxygen and nutrition to the baby would have attained its maximum size and after that its ability to function normally reduces. This means that the baby may not get enough oxygen required for their health, which can lead to severe birth disorders such as cerebral palsy.
• Meconium Aspiration: A post-term pregnancy can also lead to a condition called meconium aspiration, in which the baby breathes in the amniotic fluid which causes oxygen deficiency and leads to lung disorders in the infant.

For mothers, there could be a range of health complications such as infection, postpartum haemorrhage, C-section and even perineum injuries.

A full-term pregnancy is best for the baby and the mother. Unless there are any medical complications, it is best to go for a full-term pregnancy!
