Can someone tell me if this is definitely a platy??

I was sold this as a blood platy but is looks more like a balloon platy. Is there such a thing?? She had 5 fry and one survived a couple of months ago but her size never changed and she looks round all the time. Not preggo, just round. She is healthy and active, eats and poops normally. She just doesn't look like any of my other platies and I have a 30g tank full of them! Sorry I couldn't get a better pic...she moves around a lot! She is only about 1-11/2" long and almost that round!! Different breed or just strange looking platy? Any ideas anyone??

Hi Angela, yes it's 100% Platy, not sure if she is a balloon platy, yes they do exist she looks healthy enough. a nice fish, nothing to worry about.
