My DH was interstate when I had my ET and got a BFP Katherinelouise! We often joke about how bubs was conceived and he jokingly says he was no where near me but as I said to him I cant be held responsible as my eggs weren't with me either!
My work has been pretty supportive after a few initial hicups. I told my boss what was going on and that often I wouldn't be able to give him much notice when I had to go to appointments. He would always ask me for a weeks notice. But after a while he realised that it just wasn't possible and eventually I didn't even tell him about appointments (except the big ones where i needed the whole day off).... I start work at 7.30am so would come to the office, dump my bag and check if there was anything urgent and if not I would head to an early morning appointment. Was usually back at my desk before most people even arrived for the day.
I honestly cant say I was ever too worried about DH being there or not....but then he is a shift worker so I have to be pretty independent as I tend to have to do alot of things alone!
