What Is the Pregnancy Calendar?

Pregnancy is often described as one of the most special and transformative periods in life. To help navigate it, the pregnancy calendar divides this time into weeks, months, and trimesters. Each segment brings its own unique changes, both in the mother’s body and in the baby’s growth. The calendar offers a detailed, week-by-week guide to make these changes easier to understand.

Real-Life Experiences and Stories

In addition to medical explanations, many calendars incorporate stories from parents who have already gone through pregnancy. These stories, often accompanied by ultrasound images and photographs, provide insight into what each week feels like. Their advice, tips, and experiences help reassure new parents and make the journey less overwhelming.

Emotional and Psychological Well-Being

Emotional balance during pregnancy is as important as physical health. Expectant parents are encouraged to avoid stress, conflict, and unnecessary anxiety. Support from family and shared experiences from other parents can help reduce worries and fears. The calendar highlights this by offering both medical recommendations and kind, encouraging words at every stage.

Week-by-Week Fetal Development

• Week 1–2: The body begins preparing for conception; ovulation occurs.
• Week 3: Fertilization takes place as sperm and egg combine to create new life.
• Week 4: The embryo resembles a cluster of rapidly dividing cells.
• Week 5: The foundations of the heart, blood vessels, and respiratory system begin to form.
• Week 6–7: Limb buds appear, and the brain and digestive tract start to develop.
• Week 8–9: Facial features such as ears, nose, and lips begin forming; the brain grows quickly.
• Week 10–11: Tooth buds form, the baby is surrounded by amniotic fluid, and external genitalia appear.
• Week 12–13: All major organ systems are present; the placenta is fully formed.
• Week 14–15: The baby is covered with fine hair (lanugo) and vernix for protection. The tiny heart pumps large amounts of blood.
• Week 16–17: Facial muscles allow frowning or blinking; brown fat develops for temperature regulation.
• Week 18–20: The baby can hear sounds, reacts to the mother’s voice, and starts moving actively.
• Week 21–22: Blood cells for immunity develop; taste buds detect amniotic fluid flavors.
• Week 23–24: Subcutaneous fat begins to build; the baby takes up more space in the uterus.
• Week 25–26: Bones and joints strengthen; eyes can now open.
• Week 27–29: The third trimester begins; the brain develops rapidly, and temperature regulation improves.
• Week 30–31: The baby reacts to light and sound; movements become stronger.
• Week 32–34: Hearing is well-developed; the baby recognizes the mother’s heartbeat and voice.
• Week 35–36: Weekly weight gain increases by around 200 g; cheeks become fuller.
• Week 37–38: The baby is considered full-term and ready for birth; lanugo disappears.
• Week 39–40: Movements slow down; the body prepares for delivery.
• Week 41–42: The baby has long nails, hair, and open eyes; birth is expected at any moment.

Key Milestones by Trimester

• First Trimester (Weeks 1–13): Formation of vital organs, placenta development, early physical changes in the mother.
• Second Trimester (Weeks 14–27): Growth accelerates; the baby develops senses, and the mother feels the first movements.
• Third Trimester (Weeks 28–42): Rapid weight gain, brain development, and preparation for birth.
