Guppies usually breed continually. It is best to have a ratio of 1 male to 3 or more females so the females don't get stressed by the males chasing them all the time. It is possible (probable) the females you bought were already pregnant. They can produce 3 or 4 lots of fry without a male once impregnated. It is possible your male guppy isn't up to the job. Try another one. Don't bother putting them in a breeding trap to breed though.
