 It was surprising to see Rose Quartz look like a pregnant human woman because I wasn’t certain how she would look like when “constructing” Steven. I had so many questions forming when I was watching the episode at that part like: It makes me wonder how Rose and Greg combined their respective physical attributes if Rose can’t reproduce like human women. It makes me ‘really’ wonder a lot more than before if Rose is either female or genderless (I wish we could an answer for that soon.). Makes me really, really, 'curious' since gems can’t reproduce offspring (and only 1 offspring per gem at that) without giving up their own physical form and that gems who look ‘female’ actually look pregnant like females before they’re about to lose their physical form, what exactly happens to “male-looking” gems if they even exist, at all?

I think to understand that you have to understand that Gems, when they choose to be in their human form, perfectly emulate the human body. They have a digestive system, organs and yes, reproductive systems. So when Greg gave Rose his *ahem* "essence", she was capable of fully going through real female pregnancy, however, since she has no "human" DNA to combine with this "essence" (lack of compatible DNA being why there can be no inter-species offspring, like a dog/raccoon or a minotaur) like what would happen with a fully human child, she likely had to use her own magic to complete the creation of a zygote which would then lead to full blown pregnancy. In short, she had to use her own gem or else no baby was even possible, so yeah, she was likely actually pregnant in a very human way because her body was very authentically human.

Of course this is all speculation, the writers could easily change something as to make it "possible" for gems to experience human pregnancy in some other way. For right now, they're just banking on the suspension of disbelief, which for fantasy, is pretty much a prerequisite of viewers anyways.
