Jen, the best way I have come up with to describe a "carrying female" is as follows. Think of the space shuttle with the big fuel tank below. When they are 14+ days into gravidity( I hope that is a word), they have a very defined ridge back, with what looks like a very round payload below. I hope that makes sense. It can be funny looking at times, but they are perfectly fine. You have to remember tha they use up the grand majority of their fat stores while wrapping eggs, and filling them with the nutrition that they babies will need for the next 60 days. This is the reason that breeding id so taxing on a female. Hope that helps to calm your nerves.
