Blog Post: Fertility and Pregnancy: What to Expect After Conception
Pregnancy is a beautiful journey, but it can also be a rollercoaster ride of emotions and changes. From the moment of conception, a woman’s body begins to undergo significant transformations to support the growth and development of a new life. In this blog post, we will discuss what happens in a woman’s body after conception and what to expect during the first few weeks of pregnancy.
The First Trimester: Weeks 1-12
After conception, the fertilized egg travels down the fallopian tube and implants itself in the lining of the uterus. This process is known as implantation and usually occurs around 6-12 days after fertilization. Once the egg is implanted, the body begins to produce the pregnancy hormone, human chorionic gonadotropin (hCG). HCG is responsible for maintaining the lining of the uterus and supporting the growth of the embryo.
During the first few weeks of pregnancy, a woman may experience some early signs and symptoms, such as breast tenderness, fatigue, and nausea. These symptoms are caused by the hormonal changes in the body and are usually mild and manageable. It is also common for women to experience some spotting or light bleeding during this time, which is called implantation bleeding and is considered normal.
As the pregnancy progresses, the baby’s major organs and body systems begin to form. By the end of the first trimester, the baby’s heartbeat can be detected through an ultrasound, and the baby is about the size of a plum.
The Second Trimester: Weeks 13-28
The second trimester is often referred to as the “golden period” of pregnancy, as many women feel their best during this time. The symptoms from the first trimester, such as nausea and fatigue, usually disappear, and the baby’s growth and development accelerate.
During this trimester, the baby’s sex can be determined through an ultrasound, and the baby’s movements become more pronounced. Many women also begin to experience a noticeable weight gain and a growing belly.

In addition to physical changes, many women also experience emotional changes during the second trimester. As the baby grows and becomes more real, women may feel a stronger emotional connection to their baby and may experience mood swings.
The Third Trimester: Weeks 29-40
The third trimester is the final stretch of pregnancy and is marked by significant physical changes and preparations for labor and delivery. As the baby grows bigger, the mother’s body continues to undergo changes to accommodate the growing baby. Many women experience backaches, increased body temperature, and difficulty sleeping during this time.
As the due date approaches, the baby’s head may drop lower into the pelvis, and the mother may experience Braxton Hicks contractions, which are practice contractions that help prepare the body for labor.
In the last few weeks of pregnancy, the body may also start to produce colostrum, a nutrient-rich early milk that is essential for the baby’s health in the first few days after birth.
Preparing for Labor and Delivery
As the due date approaches, many women may feel anxious and nervous about the labor and delivery process. It is essential to prepare for this stage by attending childbirth classes, talking to other mothers, and creating a birth plan.
During labor and delivery, the body experiences intense contractions to help the baby move through the birth canal. Once the baby is born, the body will continue to undergo changes as it begins to recover from childbirth and produce breast milk for the baby.
Summary:
Pregnancy is a beautiful and transformative journey, filled with physical and emotional changes. After conception, the body begins to produce pregnancy hormones and support the growth and development of the baby. The first trimester is marked by early signs and symptoms, while the second trimester is often referred to as the “golden period” of pregnancy. The third trimester brings significant physical changes and preparations for labor and delivery. It is essential to prepare for labor and delivery by attending childbirth classes and creating a birth plan.
