In VOY: Before and After, Kes and Tom Paris are married. Paris talks of the Year of Hell, when they lost Janeway and B'Ellana who was very special to him (the budding romance shown throughout the series). Later Kes backward time jumps to the Year of Hell where she is giving birth to Linnis, their daughter.
Now, I know the Ocompa have short life spans, but Paris has just recently (within a year) lost this very special person, dated Kes, married Kes, got her pregnant and gone through the pregnancy, all while they're literally living the 'Year of Hell'. It doesn't seem to stack up...
