Scheduling Around the Unknown

How do you plan around something major that could happen any time during a four-week-plus span? It's like if you were planning a wedding that could happen on the 15th...but it might also be on the 1st or 27th, just wait and see.

For the pregnant woman who also juggles graduate school and multiple work projects, this whole planning thing is a real challenge. Take school, for example. The new semester starts in January and ends the last week of April. I'm due April 16, so if this holds, I'd only miss the final class or two of the semester. But it's best to be prepared if things change. So I've spent about a month talking to professors and an academic advisor, trying to figure out plans and contingency plans. Just when I think it's been sorted out, one of the courses I picked is now already full.

Work is a whole other issue, one that I haven't even begun to really think through yet.
