Many male guppies have 'black spots' but if by "black spot" you mean "gravid spot" then no, a male guppy can not be 'gravid' because gravid is the equivalent of "pregnant" and male guppies can not get pregnant.

Most fish do not get pregnant in the same way that mammals do. They lay eggs instead of carrying developing offspring internally. The time it takes for fish eggs to hatch varies depending on the species.
Depending how old it is, if it is an adult female and it is in with male guppies then it is very likely that it is pregnant. (:
