Understanding the Pregnancy Timeline
Pregnancy is typically divided into three trimesters, each marked by significant changes and developments. Your due date is calculated based on your last menstrual period, leading to a typical 40-week timeline. Here’s a breakdown of what to expect during each trimester and the crucial weeks within them.
First Trimester: Weeks 1–12
Week 1-2: The Beginning of a New Journey
- Menstrual Cycle Understanding: Weeks 1 and 2 comprise the menstrual cycle, which includes ovulation and the potential for conception.
- Ovulation: Fertilization occurs if sperm meets the egg during this time.
Week 3: Conception and Implantation
- Fertilization: If conception occurs, the fertilized egg travels to the uterus.
- Implantation: Around the end of this week, the embryo implants itself into the uterine lining, marking the beginning of pregnancy.
Week 4: Early Signs of Pregnancy
- Missed Period: One of the first signs of pregnancy may be a missed menstrual cycle.
- Hormonal Changes: You might start to experience nausea, breast tenderness, and fatigue.
