Pregnant or just fat fish?

I have three fish I thought were pregnant. Two Black Molly's and a Sword.
They have huge bellys, and from my experience with fish from fishing, would
appear to be pregnant. But its been too long I think. SOmeone here said they
should have given birth within 30 days. Well its been a good two months and
they just seem to stay fat. Am I possibly overfeeding just making them fat
or are they pregnant and its just not time yet?

What type of Mollies are they?
If they are the Balloon Mollies their belly will look rather large
anyway.
Over feeding is also a possibility.
Mollies have a gestation period of 28 days.
However, they can hold sperm from one mating, and have several batches
of fry from it.
(neat thing that is....saving sperm for later use)
