Moving pregnant livebearing fish is stressful. Under stress, the female can hold the fry indefinitely until conditions are favorable for fry survival. I would perform a larger than normal water change and make the new, treated tap water a bit warmer. Add a bit of standard aquarium salt to the new water, it has a calming affect on the fish. A healthy teaspoon for every 5 gallons of replacement water is enough. The amount won't bother any other fish and won't harm plants.
Give the female a couple of days to get used to her new situation. If you don't see fry, then return her to normal living conditions. Start feeding all the fish a little more and a little more often. If the female has the fry after you've returned her to normal tank conditions, the well fed adult fish will be less likely to bother the fry.
I don't move my pregnant livebearers. I do feed all my fish more often, so the adults aren't hungry. I also heavily plant the surface with Hornwort and Anacharis. These plants help maintain a steady water chemistry and give the female and fry places to hide. So, I have a high fry survival rate.
