Some may disagree with me, but I’m not 100% convinced she is gravid right now. The reasons for this is even though she is really plump and even looks a little lumpy, you say she has only ever been green and not shown any other colors. However, she is at the age when these changes are due to occur at any time and you need to be prepared. In your very first pic of her, I think she is darker colored from the stress/pain of the burn rather than having eggs. It is sometimes hard to tell, but this is what I think.
