Now you’ve gone and done it and fertilized an egg. Nice work.

The fertilized egg is now a zygote. Which I originally thought was the creature Gandalf fought in the Lord of the Rings, but that was a Balrog. My bad.

It travels down the fallopian tube for a few days and divides to form a ball of wee cells that are even smaller than the period at the end of this sentence.

The zygote continues to divide, creating an inner group of cells with an outer shell (I like to envision an M&M but I doubt that’s the case) becoming a blastocyst. The blastocyst implants itself on your uterine wall around day six.

3 Weeks Pregnant Cheat Sheet:

  • Sperm and egg have met and created a zygote in one of your fallopian tubes
  • The zygote starts dividing to form a cluster of cells (a morula ) while traveling down the fallopian tube toward the uterus.
  • You have around 259 days before you give birth.
