Your Pregnancy Journey Guide
A standard pregnancy is considered 40 weeks, starting from the first day of your last menstrual period (LMP). It's important to know that the "due date" is an estimate—only about 4% of babies arrive on exactly their due date. Most healthy babies are born between 38 and 42 weeks.
1. The Three Trimesters Explained
- First Trimester (Weeks 1-12): A period of rapid development. Major organs form. Symptoms often include morning sickness and fatigue. It is vital to take prenatal vitamins with folic acid.
- Second Trimester (Weeks 13-26): The "honeymoon phase." Energy often returns. You may feel the baby move (quickening) around week 18-22. The anatomy scan usually happens at week 20.
- Third Trimester (Weeks 27-40): The baby gains weight rapidly. You might experience back pain and heartburn. This is the time to finalize your birth plan and pack your hospital bag.
2. Common Early Signs
- Nausea: "Morning sickness" can happen any time of day.
- Fatigue: Your body is working overtime to build a life support system (placenta).
- Frequent Urination: Hormonal changes increase blood flow to kidneys.
- Mood Swings: Rapid hormonal shifts are normal.
3. When to See a Doctor
Schedule an appointment as soon as you get a positive test result. Regular prenatal care reduces the risk of complications significantly. If you experience severe abdominal pain or heavy bleeding, seek help immediately.
