Questions about maternity insurance, what to expect during pregnancy, how to get pregnant (yes, that is a serious question), and other worries/questions that expecting or soon-to-be expecting couples have don't really fall under the "parenting" category; they're more-or-less fall under "pre-parenting."
Many of the answers to the questions above would also be highly subjective - and wouldn't fit in with the Stack Exchange model at all.
The Parenting.SE target-audience are the foremost expert in these areas as they have mostly recently experienced it (I'd argue that they are, collectively, more of an "expert" than the experts/doctors in these opinionated matters).
