I bet you were talking about my thread. I admit that I never went too in depth with the anatomy as I am no Biology major (but I can tell you how language works). I just assumed that many of the deeper workings (like the organs moving to make room for the fetus) would be the same as normal human women. I also left out details about birth as I really do not care for birth at all.
I did my best to include little tidbits based off of other animals (like mermaids being born able to swim and bunnygirls having incisors that constantly grow like those of rabbits), but I started to become fairly lazy towards the end as I felt I was repeating the same things over and over again (with some of the species being so similar, that I assumed that people would just refer to past guides for some details). I also left quite a bit up to interpretation as real human pregnancies can vary quite a bit as well.
I am sorry I did not mention anything about hormones, constipation, hemorrhoids, or having to pee frequently, but I am no medical expert; I know more about syntax and morphemes than I do about synapses and medicine. (I also wanted them to be a bit fun).
