The first trimester, lasting from conception to week 13, is a crucial period of rapid development for the embryo and significant hormonal and physical changes for the pregnant person. Many of the common, and sometimes uncomfortable, pregnancy symptoms begin during this phase.
Fetal development in the first trimester
The first trimester is the most critical period for fetal development, as all major organs and body systems are formed during this time.
- Weeks 1–4: Development begins with conception, when the sperm and egg unite to form a single-celled zygote. Over the first few weeks, the cells rapidly divide as the blastocyst travels to and implants in the uterine wall. This triggers the creation of the placenta, umbilical cord, and amniotic sac.
- Weeks 5–8: The embryo grows arms, legs, and distinct facial features. The brain and spinal cord form from the neural tube, and the heart begins beating at a regular rhythm. By the end of this period, the embryo becomes a fetus and is about 1 inch long.
- Weeks 9–13: Fingers and toes are fully formed and lose their webbing. The fetus develops fingernails, and the external genitals are present, though not yet visible on an ultrasound. The fetus can move its limbs and make a fist, though the mother cannot feel these movements yet.
Maternal changes and symptoms
Rising hormone levels cause significant physical and emotional changes during the first trimester. Symptoms vary widely for each individual and pregnancy.
- Nausea (morning sickness): Can occur at any time of day and is one of the most common early signs. Eating smaller, frequent meals and trying ginger can help ease the symptoms.
- Fatigue: Extreme tiredness is very common due to increased progesterone levels and the body’s increased workload.
- Breast changes: Hormonal shifts can cause breasts to feel sore, swollen, or tender. The areolas may darken, and veins may become more noticeable.
- Frequent urination: The uterus expands and presses on the bladder. The kidneys also process more fluid, leading to an increased need to urinate.
- Mood swings: Dramatic hormonal fluctuations can cause heightened emotions, which may shift from elation to anxiety or irritability.
- Cravings and aversions: Many people develop new likes and dislikes for certain foods and smells. A heightened sense of smell is also common.
- Bloating and constipation: Higher levels of progesterone can slow digestion, leading to bloating and constipation.
First-trimester prenatal care and precautions
As soon as you find out you are pregnant, it’s important to schedule a prenatal appointment to ensure a healthy pregnancy.
- Prenatal visits: Your first appointment will involve a thorough medical history review, a physical exam, and blood tests to check blood type, screen for infections, and measure iron levels.
- Genetic screening: Your provider may discuss optional genetic screening tests, such as first-trimester screening for chromosomal abnormalities.
- Lifestyle changes: To protect the developing fetus, you should immediately stop or avoid:
- Alcohol, cigarettes, and recreational drugs.
- Foods like raw or undercooked meat, unpasteurized dairy, and high-mercury fish.
- Contact sports or strenuous activities that risk abdominal injury.
- Excessive caffeine (limit intake to under 200 mg per day).
- Healthy habits: Maintaining your well-being helps support fetal development.
- Take a prenatal vitamin: Be sure to take a daily vitamin containing folic acid, iron, and calcium.
- Eat healthy foods: Focus on a balanced diet of fruits, vegetables, whole grains, and lean protein.
- Stay active: Continue exercising moderately, resting when you feel uncomfortable.
- Manage stress: Get plenty of rest and stay hydrated.
When to call your doctor

- Heavy bleeding or severe cramping
