Don't really know how to respond to that, except to say that when the spark of life is involved, I believe that God's definitely "nearby".
This near-miraculous event sure seems like a blessing, to me...
Given that God creates the child's immortal soul, that has to be correct.
I certainly agree that the Holy Spirit is the “Lord and Giver of Life” to every child conceived, even if conceived wrongly or unnaturally. Yet this a very common thing: because children, of incomparable God-given dignity each and every one, are too often brought into existence by unseemly means: surrogacy, prostitution, careless fornication, IVF, as lab experimental subjects, or even by the rape of captured women, as ISIS does.
Each of these children, of course, is beloved in the eyes of the Lord of Life. That doesn’t mean the *way* the child was conceived, was the way God would have us do.
