What happened if there are no more males?

I bought three fish , two light and one really orange Micky . well before I knew one of the light ones was pregnet she had two fry. Lil down the road the really orange one died. I think that was the male? The light ones have to be female. One of the light ones is still really huge and she looks like she still has eggs in her. But if there is not a male Micky in the tank will she be able to still have those eggs or fry???? She already had two around march 29 th but no more since . What do I do?????
