Schrodinger's cat is a confusing example to be used for quantum mechanics. The poor cat is used as a classical detector of whether a quantum dynamically controlled process, i.e. the probability of its happening follows QM probability distributions, happened.
A geiger counter would do the same. Before a hit, the atom has not decayed, after the hit it has. Before the hit of the atom on the poison capsule the cat is alive, after the hit it is dead. The noise of the geiger counter is much more humane as far as killing a cat goes.
In your case, the quantum mechanical probability happens at the molecular level when ovum and sperm meet. All the rest, waiting for birth to see which way the probability went, or a scan to look at the body, ... are classical macroscopic detectors of an already occurred quantum mechanical probable throw of the "dice".
