I've settled on the phrase "pleasant surprise" to describe our current situation. We'd planned on trying to have kids in the near future, so this really just moved our timing up by a few short months. However, those were kind of a crucial couple of months. Consider the following time table:
~June 23rd: LMP (don't ask if you don't know)
~Dec 7th: 24 weeks and the bleeding edge of viability
~Jan 4th: 28 weeks and the date of the big job conference in my field
~Jan 11th-Mar 1st: 29-36 weeks and the time that I'll (hopefully) be having flyouts for job interviews.
~March 30th: my due date
In case you missed it (or lack a phd in pregnancy-related math) that means that I'll be doing my first round of job interviews at ~6 months gestation (which is, bizarrely, 7 months of pregnancy) and I'll be flying around the country giving talks at 7-8 months gestation.
