After 4 days I put her back in the main tank (because she has a male platy friend she likes to swim around with), and she got bigger yet again. It is the weirdest thing. She still hasn't dropped, but is square, and i swear she has been pregnant for months.
Has anyone seen this?

Okay, so you have a platy who gave birth to two fry...so right after she started birthing you moved her to a 55g--into a breeder net?
Any chance she had the rest of the fry and just ate them (while you were asleep/gone?) Remember, they are pretty hungry after they birth out--having all her fry that close/stuck in the net can be like a free meal.
Secondly, if I'm not mistaken they only fry out every 5 weeks (give or take)...so if she gave fry about a month ago, then why are you so worried? There is still at least a few days to the 5 week mark...if she looks like she's getting close, she probably is. Just keep an eye on her. (And keep her stress levels LOW to improve the chance of her, and her fry of surviving).
I don't use breeder nets for live-bearers... If you have a reasonable number of places to hide, all the strong/smart/healthy ones will survive and the weaker will be doomed due to natural selection--just the same as many breeders will cull the weaker ones.
I've had guppy fry survive with a 50% + rate while just leaving them in the large tank (full of adults). Give 'em plants and rocks/decorations to hide in and don't worry about it (JMO)
