Thanks for your story; I became well aware of the idiosyncracies of the body during my 5 pregnancies, lol.

You are mistaken to think in medical terms conception and fertilization are synonymous,

I don't. See #20 & 25.

You yourself refer to the "conception" of your grandchild. I presume you meant, technically, the fertilization process that created him.

conception has taken place when the fertilized egg makes it to the uterus and implants. A fertilization of an egg in a petri dish is not to me conception. Medically a zygot is the term for just a fertilized egg. The union of two gametes that may proceed to be a fertizilized egg.
