Congratulations on your pregnancy! It’s an exciting time, and you’re probably eager to know everything you can about your growing baby.

Size and Shape

At four weeks, your baby is about the size of a poppy seed, measuring just 0.04 inches. It might not seem like much, but that little seed is starting to take shape. The fertilized egg has divided into multiple cells, forming a ball known as a blastocyst. The blastocyst will soon implant itself into the lining of your uterus, where it will continue to grow.

Organ Development

Although your baby is still tiny, the organs are beginning to form. At this stage, the neural tube is forming, which will eventually become the brain and spinal cord. The heart is also developing, and a primitive circulatory system is beginning to take shape. Your baby’s digestive system, lungs, and kidneys are also starting to form.

Movement

At four weeks, your baby is still too small to be felt moving, but that doesn’t mean there’s no activity. The cells of the blastocyst are dividing rapidly, and the ball is starting to change shape. The tiny heart is beating, and blood is starting to flow. Your baby might even be starting to move a little bit, although you won’t feel it yet.

Mom’s Symptoms

At four weeks, you might not even know you’re pregnant yet. Some women experience mild symptoms, such as cramping, spotting, or breast tenderness. Others don’t feel any different at all. If you suspect you might be pregnant, it’s a good idea to take a home pregnancy test or make an appointment with your doctor.

Conclusion

At four weeks, your baby might be tiny, but it’s already starting to take shape. The organs are beginning to form, and the heartbeat is starting to beat. Although you might not feel any different, your body is hard at work supporting your growing baby. Enjoy this exciting time, and don’t hesitate to reach out to your doctor if you have any questions or concerns.
