Since DH is away and your BW is from Monday I would say go for it this time. Work will always be there and you can take a break from ttc next month if you need to. You've come this far. This is the one area that is so difficult for me since Cooper is close enough to monitor but far enough for work to get really irritated with me. My suggestion is to get to bed now and be at the office close to when they open for BW. Not sure if you also need an u/s or how soon they start. Just maybe drink at extra coffee. I know it will be a long day but the key is to leave early to a)beat the traffic and b)get back to work as soon as you can. Good Luck!!!!
