I think most people who oppose abortion (and I guess probably many who don’t) would say that the morphology or size of the embryo isn’t going to have a big impact (if any) on its moral status.
I do (respectfully, I hope) disagree regarding contraception as well—I tried to give some reasons for that here: https://forum.effectivealtruism.org/posts/6ma8rxrfYs3njyQZn/a-case-for-voluntary-abortion-reduction?commentId=GoTAdivEoWeurn5Fv (forgive me for being basic and not knowing how to link to comments properly)
