Your male guppy is female and with child.
All that is needed is a male guppy in with her.
it may be a femake or a FAT guppy
It might want to mate with it.
yes there are. that is how they get mates.
That does not happen with guppies. They stay the same sex for life.

what u expect? a miracle?????? Actually it's possible if you recently purchased your females from a pet store or your male recently died. Female guppies can hold sperm from a male guppy for a number of birth cycles.
If the fish has a "GONOPODIUM" it is definitely a male.
