A Blastoclyst is potential life but not life itself.

I don't understand what you are saying. How can it not be alive?

It can easily be said that a newborn baby only has the potential for life.

A blastoclyst is alive the same way a single celled organism is alive. Alive technically, but it doesn't feel pleasure or pain, think, learn, or have even a rudimentary self awareness the way humans do. Its merely undiferentiated tissue in the process of running some genetic and chemical instructions which will eventually turn it into a human being if all goes well.
