8th week is so early the risk of loosing the embryo naturally is still very high. I know more than one couple that lost embryos at that stage - my mother in fact, multiple times. So that blob of cells is very much still in the “might turn into a human” state.
My mother-in-law had this happen several times as well. But "might not turn into a human" is, in my opinion (and my mother-in-law's), insufficient reason to allow abortions for any reason, up to (and in some cases, after) the moment of birth.
You might turn out to be a murderer; you wouldn't appreciate it if we preemptively threw you in jail.
