Star Trek: Chekov's Baby

Set after the events of Star Trek: Generations. Saavik has since returned to the crew, and she and Chekov have already "done the deed" (conceived their child) by the time the story starts. This story, aswell as being mpreg, is also a multi-way crossover, as Chekov and Saavik become part of the Voyager crew, which will later merge with the TNG crew, and the other crews too.
