Swordtail...pregnant Again?

[sublime8]

I have a swordtail who just gave birth aroun 1 1/2 to 2 weeks ago. The problem is that she looks really pregnant again. There has been no change in her, or any of the other fishes, behavior. So I am wondering if it is possible for her to be this pregnant after only 2 weeks, or if she is possibly sick. If anybody knows anything about this or has alot of experience with swordtails that would be great. Thanks for all your help and I am sure that collectivly you can all help me figure out what is going on.
