Pregnancy: Symptoms, Trimesters & Information

  • Synopsis: Information on pregnancy and being pregnant including symptoms trimesters and conception due date calculators.

Definition: Defining the Meaning of Pregnancy

In human reproduction, pregnancy (or gestation) is the development of one or more offspring, known as an embryo or fetus, in the uterus of a woman. A multiple pregnancy involves more than one embryo or fetus in a single pregnancy, such as with twins. Childbirth usually occurs about 38 weeks after conception.

Healthy pregnancies start before a mother becomes pregnant, even before they consider motherhood. Women may benefit from basic pre-pregnancy planning and regular visits with their health care provider. Prenatal care visits are important to both the baby and the mother. There are some things that a mother might do when they are pregnant that could harm their baby, to include drinking or smoking. Certain medications may also be a problem, including ones that a doctor has prescribed. It is important to eat a healthy diet and drink plenty of fluids. Early in the pregnancy, a mother might experience nausea or morning sickness, or need more rest.

The average pregnancy lasts approximately forty weeks, grouped into three trimesters.

During the first trimester, a mother's body experiences a number of changes. A mother's hormones change and affect nearly every organ system in their body. The changes may initiate symptoms, even in the first weeks of the pregnancy.

The majority of women feel the second trimester of pregnancy is easier than the first one.

It is important to remain informed about pregnancy during this trimester. A mother may notice symptoms such as fatigue and nausea are not disappearing and new, more noticeable changes to their body are occurring. A mother's abdomen will expand as their baby grows; before the second trimester is over they will feel their baby starting to move.

The third trimester may bring some of the same discomforts a mother experienced during the second trimester.

In addition, many women can find it more difficult to breathe and notice they have to use the bathroom more often because their baby is getting bigger and placing more pressure on their organs. Not to worry, the baby is fine and these issues will lessen after the baby is born.

Motherhood is one of life's greatest responsibilities and joys. By doing everything you can to prepare for parenthood now, before your baby is born, the transition to parenthood can be a lot easier.

Signs and symptoms of pregnancy may include:

Things you can do include pursing education related to:

As the due date approaches, look for any sign that labor is about to begin, no matter how small. Mothers may notice their baby has dropped, or moved into the lower part of their pelvis. A pelvic exam during a prenatal visit to a doctor can reveal changes to a mother's cervix they might not feel, yet suggest their body is getting ready.

Once the baby is born, spend the first hours of the baby's life letting your baby know your voice and study your face. The baby can see up to about two feet away. Babies are born with sucking and grasping reflexes; put your finger in the baby's palm. Feed your baby when they show signs of hunger.

Halving Risk of Pre-term Birth for Some Twin Pregnancies

A study, involving researchers from the University of Adelaide's Robinson Research Institute, reviewed all of the previous large studies conducted into the use of progestogen hormones, which have been trialled over the past 10 years to help prevent preterm birth in twins. The results, published in BJOG: An International Journal of Obstetrics and Gynecology, show that an important discovery had been missed in each of those previous studies.

Until now the research has demonstrated that there has been no benefit from the use of progestogen hormones in preventing preterm birth for women with a twin pregnancy. Thanks to this international review, we can now see that there is a very specific benefit to one group of high-risk pregnancies: women who have a short cervix, who are pregnant with twins.

Twin pregnancies are very much at risk of preterm birth, with half of these pregnancies delivering before 37 weeks gestation. For women with a short cervix who are also pregnant with twins, this is what I would call a super high risk category for adverse outcomes, either for infant death or for serious health problems after birth. We found that by using progestogen hormones, there was a 50% reduction in risk of preterm birth for this group of pregnancies.

Statistics: World Pregnancy

The incidence of pregnancy among the female population, as well as the ages at which it occurs, differ significantly by country and region, and are often influenced by a multitude of factors, such as cultural, social and religious norms; access to contraception; and the prevalence of (higher) education.

The total fertility rate (TFR) in 2013 was estimated to be highest in Niger (7.03 children born per woman) and lowest in Singapore (0.79 children/woman).

In Europe, the average childbearing age has been rising continuously for some time.

In Western, Northern, and Southern Europe, first-time mothers are on average 26 to 29 years old, up from 23 to 25 years at the start of the 1970s.

In a number of European countries (Spain), the mean age of women at first childbirth has now even crossed the 30-year threshold.

This process is not restricted to Europe. Asia, Japan and the United States are all seeing average age at first birth on the rise, and increasingly the process is spreading to countries in the developing world like China, Turkey and Iran. In the US, the age of first childbirth was 25.4 in 2010.
