Your Complete Guide

Tracking your pregnancy journey is exciting, especially as you begin to see the changes in your body and the development of your baby bump. Each week brings new milestones, from the conception process to the growth of your baby. In this guide, we’ll break down the stages of pregnancy and the development of your baby bump week by week.

Week 1: The Pre-Conception Stage

Week 1 is technically the start of your pregnancy, but conception hasn’t yet occurred. During this time, your body is preparing for ovulation, where an egg will be released from your ovary and ready to be fertilized. This phase sets the stage for the journey ahead.

• Understanding Ovulation: This is when the egg is released from your ovary, making it ready for fertilization.
• The Menstrual Cycle: It’s important to understand how your menstrual cycle works, as it plays a key role in conception.
• Early Symptoms: At this stage, you may not notice any major physical changes, but subtle signs like changes in cervical mucus could appear.

Week 2: Conception Occurs

Conception typically happens during week 2 when the sperm meets the egg, forming a fertilized zygote. This is the beginning of your pregnancy. The fertilized egg then starts dividing and forming an embryo, which will eventually implant itself into your uterus.

• Fertilization: The sperm and egg combine, forming a zygote that starts dividing into a tiny embryo.
• Hormonal Changes: Your body begins releasing hormones that prepare your uterus for implantation.
• Physical Changes: At this stage, you may not notice any major changes, but early signs like mild cramping or fatigue could occur.

Week 3: Early Embryonic Development

At week 3, your baby is growing quickly. The embryo is developing key structures, such as the neural tube, which will eventually form the brain and spinal cord. During this stage, the placenta and umbilical cord are also beginning to form.

• Neural Tube Formation: This early structure will become the brain and spinal cord.
• Placenta and Umbilical Cord: The placenta begins to form and starts providing nutrients to the embryo through the umbilical cord.
• Physical Symptoms: Many women may experience fatigue, breast tenderness, or mild cramping during this phase.

As your pregnancy progresses, it’s important to stay informed about the developments happening in your body. To understand these changes better, you can refer to BabyCenter’s Pregnancy Week-by-Week.

Week 4: Missed Period and Positive Test

By week 4, your missed period is one of the first signs of pregnancy. A home pregnancy test can confirm what you may already suspect: you’re pregnant. Hormonal changes start to cause physical changes in your body as well.

• Home Pregnancy Test: If you’ve missed your period, a home test can help confirm pregnancy.
• Hormonal Shifts: Expect hormonal changes that might lead to morning sickness, fatigue, and an increased need to urinate.
• Early Pregnancy Symptoms: You may experience nausea, food aversions, and increased tiredness.

At this stage, your baby bump won’t be visible yet, but your body is already adjusting to pregnancy.

Week 5: First Trimester Begins

At week 5, you’ve entered the first trimester, and your baby’s development is picking up pace. While you may not see your baby bump just yet, many key developments are occurring.

• Organ Development: Your baby’s organs, such as the heart, liver, and digestive system, are beginning to form.
• Limb Buds: Tiny limb buds start developing into arms and legs.
• Pregnancy Symptoms: Expect more noticeable symptoms such as morning sickness, fatigue, and tender breasts.

Your baby bump is still small, but your body is undergoing significant changes as it prepares for the months ahead.

Week 6: Baby’s Heartbeat and Growth

By week 6, your baby is growing quickly, and you might be able to hear your baby’s heartbeat on an ultrasound. This is an exciting time as your baby’s organs are maturing.

• Heartbeat Detection: At this stage, your baby’s heartbeat may be detected with an ultrasound.
• Rapid Growth: Your baby is rapidly growing, and their organs are becoming more developed.
• Physical Symptoms: You may experience increased fatigue and symptoms of early pregnancy, like nausea.

While your baby bump is still not visible, your baby is beginning to look more like a tiny human.

Week 7: Facial Features Begin to Form

At week 7, your baby’s facial features are starting to take shape, including the formation of the eyes, nostrils, and mouth.

• Facial Development: Eyes, nostrils, and the mouth are beginning to form.
• Limb Development: Your baby’s arms and legs continue to grow, and small fingers and toes start to form.
• Changes in the Mother: As the pregnancy progresses, you may feel more tired and experience emotional changes.

Even though your baby bump is still small, these developmental changes are laying the foundation for the growth ahead.

Week 8: Limbs and Movement

By week 8, your baby’s arms and legs are developing more fully. Small movements may even be detectable on an ultrasound, although you likely won’t feel them just yet.

• Limb Formation: The baby’s arms and legs are now well-formed, and tiny fingers and toes are visible.
• Early Movements: Although still very subtle, your baby may start moving.
• Physical Changes: Expect more noticeable pregnancy symptoms such as fatigue and morning sickness.

Your baby bump will still be small, but your baby’s development is progressing rapidly.

Week 9: Organ Maturation and Growth

At week 9, your baby is growing rapidly. By now, all of their vital organs, including the heart, lungs, and kidneys, are in place and continuing to develop.

• Organ Maturation: Your baby’s organs continue to mature, including the liver, kidneys, and lungs.
• Growth: The baby is growing quickly in size and weight.
• Mother’s Changes: You may experience typical pregnancy symptoms such as morning sickness, fatigue, and frequent urination.

At this point, your baby bump may be visible, depending on your body type.

Tracking Baby Bump Progress

As your pregnancy progresses, tracking your baby bump becomes increasingly important. Regular check-ups and ultrasounds can help ensure your baby is developing on track.

• Fundal Height: A healthcare provider will measure your fundal height to track the baby’s growth.
• Ultrasounds: Regular ultrasounds provide a clearer picture of the baby’s development.
• Physical Changes: As you move through the second trimester, your baby bump will become more pronounced.
