How pregnant was Rome?

A woman is either pregnant or not. It is sort of Boolean, right? As Rei and Rome arrive at Deucado at the beginning of Part 2 of Rome's Revolution, Rome is described as 'looking as pregnant as humanly possible'. The idea here was the Vuduri were a race of human beings somewhat smaller and somewhat slighter than us. Whether this was due to natural selection or genetic drift was never made clear.

Our 21st century hero Rei Bierak is often described as "towering over the Vuduri" not just because he was nearly six feet tall but also because of his musculature. So we have the situation set up where a relatively large man and a relatively tiny woman procreate. The baby, to be named Aason, was assumed to be larger than a standard Vuduri baby. This led to problems prior to his birth. We also know that Rome suffered from polyhydramnios and the implication was it was due to Aason being too large. It was only later we find out that Aason actually caused the condition because he "could not find" his mother and he "pushed" too hard.

So, basically, it looked like Rome had swallowed a watermelon. Her abdomen was extremely distended. Just as they were about to land, Rei tried to make a joke about it:

     “Calculations complete,” MINIMCOM announced. “One minute to jump.”
     “Great,” Rei said. He rubbed his hands together. Then he looked over at Rome’s abdomen again. “Honey, for landing, we’re going to have to squeeze you into a pressure suit, just in case, right?”
     Rome wagged a finger at him. “I will manage,” she said tersely.
     Rei continued. “Well, we have a spare. I was thinking we could stitch two together…”
     “Whatever you are about to say,” Rome interrupted, “do not dare!” Her glowing eyes were flashing but there was a smile on her face.
     Rei laughed. “I understand.”

Obviously, the joke did not go over well. I'm still not 100% sure why they had to wear pressure suits for landing anyway. But to address the question posed in the title of this article, how pregnant was Rome? Answer: very!
