Yes, that is true….and sad. But the 40-day limit is also based on compassion so that the termination, if it is to occur, happens in the zygote stage before it can feel pain.Not answering for Ding...
...Again simply something to consider...
Can a human being exist without the first forty days of cellular growth? I'm noting something wonderful is happening in human creation those first 40 days. A life is being refused existence when abortion occurs.
How tragic that an embryo, just weeks away from birth and the start of a life of toys, and school, and friends, and first kisses, and high school activities, and then the excitement of college, one’s first apartment, and a career, and perhaps marriage, and children, and grandchildren, and enjoyable travel, and relaxing days at the beach, and beautiful music, etc., is not only robbed of all that - but dies in pain.
At the very least, we can limit the term to where pain isn’t felt or processed.
