I've kept these fish for several years and keep all my fish togther. Removing pregnant females from the the tank is stressful at best and you don't want to lose any fry.
Keep all your fish together and feed frequently. Adult Guppies are much less likely to go after the fry if they're well fed and keep a lot of floating plants like Anacharis and Pennywort.
From fry to mature fish takes the males about three months, the females a bit longer, about four.
Keep the water conditions stable and pure, by removing and replacing half the tank's volume every week.
Just a couple of thoughts.
