dont even have to look at it to tell you the answer is yes. almost all female livebearers you get that are mixed with males will be pergo when you get them. normally its i think every 21 days if i remember correctly off hand.... 15-25 would be normal but they can have a lot more then that. i would just leave her in the tank. the other fish will eat the fry for the most part. unless you have another tank set up cycled plus space to raise all the fry i wouldnt worry about it.
You could also explore raising just a few fry, for fun. If you have space, that is. The rest will most likely become snacks!
I have a 10G that, when not in use for QT, I will try to snag fry into.
