I bought a female platy(Spot), found out she was prego, two days later I bought another (Stripe) to keep the male (Bitsy) from harrassing Spot too much. Found out the Stripe was pregnant too!, this was like two almost three weeks ago! no fry yet! Spot is skinnier agian, but Stipe looks like she is going to explode! I thought the gestation period was only 3 weeks?! maybe the fry were eaten when I wasn't looking? lol.
