Once you can state that the pre-born is a human worth protection of the laws, then there is no bright line as to how early the ban could be extended.

The claimed ends don't justify the means.
These bills, which define the child as a person, and then make "legal" provision for the killing of certain disfavored classes of these persons, are grossly immoral and completely unconstitutional.
Our Constitution ABSOLUTELY REQUIRES equal protection for ALL. There are NO exceptions. And it's NOT optional.
"No State shall deprive any person of life without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.""No person shall be deprived of life without due process of law."
