Honestly, this seems like a very promising start. The fact that it seems like she'll be able to become pregnant from various things, both human and not (given that the pregnant status at the end specifies "human") is a big plus, and I can only hope that it's not going to be a case of "she can get pregnant once in a given playthrough, and then she's just pregnant for the rest of that run". I know it makes sense to stick with that sort of thing unless you add in time skips, but to me games like this are always better with the opportunity for repeated pregnancies (or, at least, more than just one).
