As said if she with males than she is most definitly pregnant. Some of the signs to look for to tell that she is getting close to dropping her fry, is that she starts to square off, when looking at her from the side instead of looking rounded her back end will start to take on a more box shape appearance. You may or may not see a gravid spot, depending on her coloring. On some of my platys I can see a gravid spot and on my darker colored girls I never do see the gravid spot. When she is getting close she may start hiding more, amongst plants, behind the filter intake if you have an HOB, and any other area. Also some fish will start becoming more aggressive. Most wil also become uninterested in food when they are close to dropping their fry. When they are close to dropping they will start to produce a hormone which usually keeps them from eating their fry while they are dropping. If you are wanting to raise the fry you have a few choices of what you can do for setups, if you have any questions I can give you some ideas. On the note for your ratio, with livebearers it is recommended that you keep a ratio at least of 2:1 female to male. Male livebearers basically have two things on their mind to eat and to reproduce, and they can harass a single female to death. With two males to one female she will constantly be under their harrassment. With a 10 gallon you are a little bit limited on space, you may want to consider returning one of the males and replacing him with another female.
