Jeremiah 1:5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.
I like it (what a silly thing to say about Scripture), but if the soul is added at three months, six months, or even a day before birth... these statements would still be True. It does come closer that the verses that originally came to mind.
Psalm 127:2-4 Behold, children are a heritage from the LORD, The fruit of the womb is a reward.
Can we conclude from this one that the "fruit of the womb" is a reward for the entire duration?
I think in this Space, time and matter theatre we are Body, Soul & Spirit and as soon as the sperm and egg combined it was me.
It was still Jeremiah in the belly no matter what stage of the contruction.
