Knocked-up?! What do you think?

Allrighty, I bought this snake on February 23rd at a reptile show and as I was leaving the seller let it slip that she might be gravid. Here is a picture when I brought her home:

Fast forward a couple of weeks? My son takes her out to play with her and places back in her rubbermaid tub(temporary home while I was cleaning her cage) but doesn't shut the lid all the way and a few hours later I find her snuggled up together inside of a hide rock with the "female" snow corn that I bought off of craigslist back in January. I had instructed my son to place the rubbermaid tub down inside the other snake's cage(a 40 gallon breeder) to keep her warm because it was cold at the time. I panicked, put her back in her now clean tank, and cautioned my son to be way more careful, but I didn't worry because they are both females right?
Well here she is now:

I hope that these pictures are adequate. I can take more tonight if needed. I don't think that she was pregnant when I bought her because, from what I have read, it only takes up to 6 weeks for a cornsnake to lay eggs after she has had copulation. February 23rd to now is way too long. My guess is that my "female" snow is really a male. She had a shed last week some time. She ate last weekend as well. What do you guys think? Is she prego?

Yeah, that's what I was thinking that I would do just in case. She is definitely way fatter than she was when I brought her home and I haven't overfed her.

It's possible she could have retained sperm from a previous male long before you bought her and made use of that sperm when she ovulated this spring. Or, as you said, your female snow could be a male.

Yep, thought of that too. I would have had the snow probed, but the reptile store that I used to go to closed so...
