Breeding of Guppies

Question
My female guppy just had her second set of babies (the first arriving a little over a month ago).  She gave birth to 4 babies the first time (though she had them when I wasn't home so there may have been more).  This time she had three (but again, she delivered when I was out).  My question is about one of the latest babies.  It's huge!  It is the exact same size as the 1 month old guppies are!  Could she have held this one in for that month or something?  It just seemed very odd.  I didn't even realize it at first.  I was catching up the new guppies to put them in the breeder net with the others and when I went to feed them, there were 5 larger babies and 2 smaller ones.  I thought I was going crazy.  Have you ever heard of such a thing?

Answer
Hi Jessica;

I suppose it's possible, but more likely that it has been hiding all this time and you found it in your search for the new ones. They can be very hard to see. She wouldn't be able to deliver them if they are too big.
