Week 1-3 Pregnancy

The first 1–3 weeks of pregnancy often go unnoticed but are vital. Discover what happens in your body and why this early stage matters so much.

Not to worry you, but this is the time when miscarriages are most likely to occur.

At this point, your baby is just a tiny cluster of cells known as a blastocyst, made up of hundreds of multiplying cells. Amniotic fluid is beginning to form around this little ball of life, preparing to become the amniotic sac.

Although your baby is still too small to be recognized, so much is already happening to lay the foundation for a healthy pregnancy.
