I think that, from context, it was clear I was using "pregnancy" to mean "the state of being pregnant" and not referring to the nine month gestation period.
That'll teach me to contribute to pedantry-focussed subthreads. :-)
Hella Nor Cal or Totally So Cal? The Perceptual Dialectology of California

This study provides the first detailed account of perceptual dialectology within California (as well as one of the first accounts of perceptual dialectology within any single state). Quantitative analysis of a map-labeling task carried out in Southern California reveals that California's most salient linguistic boundary is between the northern and southern regions of the state. Whereas studies of the perceptual dialectology of the United States as a whole have focused almost exclusively on regional dialect differences, respondents associated particular regions of California less with distinctive dialects than with differences in language (English versus Spanish), slang use, and social groups. The diverse sociolinguistic situation of California is reflected in the emphasis both on highly salient social groups thought to be stereotypical of California by residents and nonresidents alike (e.g., surfers) and on groups that, though prominent in the cultural landscape of the state, remain largely unrecognized by outsiders (e.g., hicks).

By far, the most frequently remarked-upon slang term in the map-labeling data was hella, accounting for 47.4 percent of the slang and other lexical labels. Hella is a slang term originating in Northern California and one that remains—aside from a few brief moments in the national spotlight due to its circulation in popular culture— largely restricted to that region (Bucholtz 2006). The term, which apparently lexicalized from (a) hell of (a), functions as both a quantifier (There were hella people there) and an intensifier (He runs hella fast). Four respondents also mentioned the slang term hecka, the G-rated equivalent of hella, but this term was not counted separately, because tokens of hecka always co-occurred with hella. For Southern Californians in particular, hella represents a crucial shibboleth separating the two major regions of the state. As shown in Figure 7, respondents tended to identify hella overwhelmingly as a Northern California slang term, and its appearance in other regions of the map drops dramatically from north to south. Thus Northern California was variously labeled the hellas, Land of the Hella’s, and Hella capital, and one respondent provided an isogloss designating “the ‘hella’ line.” (In the map data, the Central Coast around Santa Barbara seemed to be the dividing line between users and nonusers of hella, and the fact that the study was conducted in this region may have enhanced respondents’ focus on this particular issue.) [*10: The respondent’s confusion may also be due to the existence of the Crips, a notorious Los Angeles–based gang.] Hella users were also negatively evaluated by Southern Californians, and the term came in for a good deal of criticism, such as Hella is not a real word and [hecka is] probably the worst word ever.
