Morphology

up + the + duff

The expression 'up the duff' meaning 'pregnant' is an informal British idiom whose overall meaning cannot be predicted from 'up' + 'the' + 'duff'—the word 'duff' is slang/dialectal and offers no transparent link to pregnancy. This lack of compositional or cross-linguistic cues makes it unlikely a B1 learner who knows the individual words would infer the idiomatic sense.

Etymology

Up the duff may come from old slang where duff meant a pudding or dough that swells when cooked and up suggests something rising. One popular idea is that this picture of a rising pudding is like a growing belly, so up the duff came to mean 'pregnant'.
