Mike,
If the snake has not defecated in the four weeks since you've had her, then that is a big problem. I cannot tell if its just the angle of the pic or the actual snake, BUT it looks very emaciated and in bad shape. Has she ever eaten at all?
Also, what size is her waterbowl? Strange question maybe but I have a friend w/ a 1st corn (yearling) who only had a water bowl the diameter of a dime (10cents). The snake was super healthy and ate regularly so it must have been obtaining water from the mice. When I saw this, I immediately convinced him to use a larger water bowl in his snake's cage.
Well, anyway, I hate to say this BUT I would think a trip to a herp vet or an experienced local herper might provide a better assessment than anyone else can since its hard to tell from the pic. I do notice the visible swelling though... Also, I find that very few snakes like baths and it can be extremely stressful if the water temp is too warm or too cool. She is definitely not ovulating or gravid from what I gather, especially if she's as small as she appears on my screen. Its been awhile since I've reviewed my herp anatomy but I'd guess there are problems like liver and kidney damage/swelling that is associated with dehydration??????? Anyone else with this knowledge, feel free to jump in...
Personally, I would rarely let a newly acquired snake go 4 weeks without getting something in its belly...but thats me and I have good experience w/assist feeding and am comfortable with a technique that works fine for me and stresses the snakes very little. IF the snake did not have that buldge, I would say to try assist feeding BUT you could make things ALOT worse very quickly, esp. if its blockage or something else much worse, like organ swelling???. I am no expert but thought I'd throw some ideas for you to think about. Also, since you posted last week, others may have more knowledge or details of your situation (temps, humidity, etc) and might provide more insight.
GOOD LUCK and BEST WISHES!
Sincerely,
Jason
