I have a three hour exam at 37w5d. Various scaremongers of my acquaintance assure me I'm going to need to get up to pee every twenty minutes or so. Really?! If so, I should probably forewarn my uni/ put in a mitigating circumstances form in advance, which I've been avoiding doing because they make it into a massive faff.
But yes - I know things aren't going to be exactly comfortable, but are people exaggerating or not, before I make a song and dance about needing extra time for loo breaks or anything?
