Yep Lindsey. I don't think she's pregnant. If there are no kittens in the next 2-3 weeks, then she has a false pregnancy - its uncommon but does happen. Reason I'm thinking its a false one is that the nipples are not the normal way in a pregnant cat. Symptoms are there, but not really.
Only other way is to get her x-rayed to see if she really has any kittens.
