Rosy swollen after brumation

I have a large female coastal that came out fat after 2 months in brumation. Shes fat from mid body to her tail like a gravid boa is. She didnt do this last time I brumated her a few years ago. Does any one know whats going on here?

I really don't know. Could she be ovulating?

Sounds like it could very well be ovulation. However, since there was some Crypto discussion earlier, I should also point out that firm mid body swelling is one of the symptoms that is often exhibited by snakes that are aflicted with Cryptosporidiosis. However, from your description I do not think you need to be concerned, as swelling from Crypto is usually more loaclized, and often gives the appearance of a mass or large cyist. This symptom is to be taken more serious when affected snakes exhibit it in conjunction with cronic regurgitation, extreme weight loss, depression, and mucus-covered cottage-cheesy stools. Your snake's swelling seems to affect the entire back half of the snake, and it just sounds more like ovulation to me.
