She will only have problem if her child would be half-drow (if she ofcourse remains in the Menzoberranzan) that what will summon questions from other nobles.
When was this ever implied or said? Genuinely curious.
Well, any source about half-drow in society of Menzoberranzan. Their fate mostly is to be sacrificed or become slaves. Absolute most of them is offsprings of male drow and woman other race. So for lolth-sworn drow female gives birth to a half-drow something equals sacrilege (and it's a bit obvious due to drow racism).
