Are my platies male or female?

So, I have 2 sunset platies, and I know that one is a female, but other one I'm not sure about. I thinks they're both females though. Could one still have fry in it's belly form when it was at the pet store? The smaller one seems to chase the bigger one sometimes, so is it probably a male?
Answers:
Platies are very easy to sex, actually.

Look at the fin on the bottom of the fish that's closest to the tail. This is the "anal fin". In females the fin is triangular shaped (when fanned out), but round looking. In males, the fin is triangular shaped but very angular. When the fin is tucked, the females' is rounded at the tip.the males' is pointy looking.

Hope that helps. =D
Males are often smaller and they're also a bit more colorful with nicer fins. And yes the female could easily be pregnant.
Ooh. I've had those before! Look at the anal fin, or the small fin about a centimeter under the tail, on the belly. If it fans out and there are 2 sets of anal fins, it is a female. If one has 1 set of anal fins that rod/stick shaped, it is male. That simple.
Males have bigger, prettier fins. His tail and the fin on his back will be noticably bigger.
She could indeed be pregers from the pet store.
the males hav a little poinier fin by there anus, the females hav a wider fin by the anus, and it could just be a really anoying fish, lik i used to hav a guppy that would always chase platies and female guppies
All livebearers are sexed the same way. Here is a picture of a male
