Week 3 of Pregnancy
Congratulations! You have officially conceived and your little bundle of joy is starting to develop.
The fertilized egg, also known as a zygote, will divide into two cells, then four, and so on until there are approximately 100 cells just days after fertilization. This ball of cells is called a blastocyst and it is already located in your uterus.
The outer cells of the blastocyst will transform into the placenta. The placenta will provide oxygen and nutrients to your baby throughout your pregnancy. It will also remove waste from their blood.
The placenta will begin producing human chorionic gonadotropin (hCG) - the hormones picked up by home pregnancy tests and blood screenings. The spike in estrogen and hCG will cause many changes in your body, especially during the first trimester, so you will soon experience the first symptoms.
Although you have already conceived, you probably won’t be able to tell until next week or a little further ahead.
