Question

You just found out that your sister conceived about seven days ago. You rush to find a book on pregnancy so that you can learn more about it. What will the book say is happening around the seventh day of pregnancy?

Answer 1

At seven days of pregnancy, the blastocyst is implanting into the uterine lining, beginning to receive nutrients and oxygen from the mother, and the hormone hCG is starting to be produced.

Step-by-step explanation:

At seven days of pregnancy, a significant event is occurring—implantation.

During this time, the fertilized egg, which has become a blastocyst, is completing its journey through the fallopian tube and attaching itself to the lining of the uterus.

This is a crucial step in the process of establishing a pregnancy as it allows the embryo to begin receiving nutrients and oxygen from the mother, which are essential for its development.

The pregnancy hormone human chorionic gonadotropin (hCG) is also starting to be produced, which is what pregnancy tests detect to determine if a woman is pregnant.
