There are apparently two independent derivations of the word "pregnant" (though the roots may join), confusingly, both adjectives. Other than "with child", there is:
"convincing, weighty, pithy," late 14c., "cogent, convincing, compelling" (of evidence, an argument, etc.); sense of "full of meaning" is from c. 1400. According to OED from Old French preignant, present participle of preindre "press, squeeze, stamp, crush," from earlier priembre, from Latin premere "to press, hold fast, cover, crowd, compress" (from PIE root per- (4) "to strike").*
