If it were an early stage pregnancy it wouldn't be detectable, and so long as there's some life that's all that is needed for the demon. With Asuramaru and other demons in a kind of stasis for long periods of time, if it wanted to, the story could address Mahiru having Guren's child. Demons can materialize physically in the world - Guren is one, so stands to reason humans with demon powers could be born.
