This week-by-week guide will provide you with an in-depth look at what to expect during each stage of your pregnancy, empowering you with knowledge and preparing you for the amazing adventure ahead.
**Week 1-4: The Beginning of Life**
During the first four weeks, the fertilized egg travels down the fallopian tube into the uterus and implants into the uterine lining. This is when your body starts producing the hormone human chorionic gonadotropin (hCG), which can be detected in pregnancy tests. By week four, the embryo forms a neural tube, the foundation of the brain and spinal cord.
**Week 5-8: The Embryonic Stage**
The embryo undergoes rapid growth and development during these weeks. Key organs and systems begin to form, including the heart, lungs, and limbs. By the end of week eight, the embryo is fully formed and known as a fetus.
**Week 9-12: Rapid Fetal Growth**
The fetus grows significantly during this trimester. Its fingers, toes, and facial features become more defined. It also starts to make small movements, such as stretching and kicking. By the end of week 12, the fetus is about the size of a plum and weighs approximately an ounce.
**Week 13-16: Moving and Feeling**
The fetus continues to grow and move around more actively. It may respond to stimuli, such as loud noises or your voice. Its heartbeat can be heard with a stethoscope. By the end of week 16, the fetus is about the size of an avocado and weighs around four ounces.
**Week 17-20: Halfway There**
At week 20, you reach the halfway point of your pregnancy. The fetus is fully formed and weighs approximately one pound. It can now hear sounds from outside the womb and even recognize your voice.

**Week 25-28: The Third Trimester Begins**
This trimester is characterized by significant fetal growth and movement. The fetus's lungs begin to mature and it starts to practice breathing. By the end of week 28, the fetus weighs around three pounds.
**Week 29-32: Preparing for Birth**
The fetus continues to gain weight and grow in length. Its skin becomes less wrinkled and its hair starts to grow. It also starts to practice crying and sucking reflexes. By the end of week 32, the fetus weighs around four pounds.
