What does orthodoxy say about abortion?

So I am soon to be orthodox, yet I am also a radical feminist.

I have always been supportive for abortion, pro chose ext.

I know that the Torah allows it if the woman’s life is at cost.

But what if it not the case, let’s just say that me and my wife are not yet ready to have a baby so we decide to abort the foetus.

Would this be considered a murder? Would I as well as my wife be legally responsible for the murder of my children?
