What is the first trimester of pregnancy?
The first trimester runs from the beginning of pregnancy until the end of the thirteenth week.
In medical terms, pregnancy is calculated from the first day of the last menstrual period, although conception generally occurs about two weeks later.
In this initial phase, the body produces essential hormones, such as progesterone, necessary to support the implantation of the embryo and the evolution of the pregnancy.
What happens in the body in the first few weeks
From the first weeks to the discovery of pregnancy
In the very first weeks, many women don't yet experience any obvious signs. However, the body is already hard at work: the embryo implants in the uterus, and significant hormonal changes begin.
Among the most common initial signs:
- unusual tiredness
- abdominal swelling
- breast tension
From the fifth to the eighth week
This is the period when pregnancy is often discovered. Hormone levels rise rapidly, and nausea, sensitivity to odors, and increased emotionality may occur.
From the ninth to the thirteenth week
The body continues to adapt. In some women, the symptoms subside; in others, they remain but become more manageable. The baby grows rapidly and takes on an increasingly defined shape.
The most common symptoms of the first trimester
Symptoms vary greatly from woman to woman. Some of the most common are:
- nausea, even if not limited to the morning
- intense tiredness
- changes in appetite
- breast tension or enlargement
- increased sensitivity to odors
- abdominal swelling
Many of these disorders are related to hormonal changes. For those who want to learn more about how to alleviate the most common pregnancy ailments , it's helpful to seek targeted advice.
Baby development in the first trimester

By the end of the first trimester, the baby already has a recognizable structure and many essential functions have been established.
