According to the Chicago Manual of Style, it's six months' notice (analogous to the examples there: an hour's delay, three days' time).Quote:

I think, though, that it would be three months pregnant. "Pregnant" is an adjective rather than a noun, so it's not quite the same structure as the other examples. But I admit I'm guessing on that one.
