So if I'm not pregnant at the moment...why bother with the title? And I'm clearly not going to be pregnant forever, right?
It's a convoluted reason...but here goes. It's a title that I identified with. The two seemed to go hand-in-hand. I haven't held any other position while being pregnant, and I've been pregnant a fair amount of time that I have been a post-doc. OK...so only 18 months (ish!). I just figure that the two together make for a bit of a unique situation, and there are challenges for undertaking both of those at the same time.
What are some of the things? Working hours being one. Grad students and post-docs notoriously work weird hours. Science doesn't stop just because it's the weekend or evening. The next being the environment. It's a lab! There are tons of hazardous chemicals, biological agents and so on. It isn't a strict "desk" job, so while the physical demands are by no means super strenuous, they are still there. Job stability. Oh boy. Post-doc positions don't last forever. Nuff said about that.
With my first child, I was technically pregnant during an "in-between" stage of my career. I'd been a post-doc for over a year prior, and had suddenly come into a loss of funding from my P.I. I still did some work in the lab, still attended lab meetings and all of that. I continued through the pregnancy doing all of that and working in teaching positions at the university and community college.
With my second (most recent), I was a full fledged post-doc and I became pregnant only about 7 months into starting the position.
Having said all of this, will I be a post-doc still when it comes time for another pregnancy? Probably! And at that point, I can cross off the the cross-off on the pregnant part :)
