The last month of pregnancy is designed* to ensure that you're happy to go into labor.
Everyone who sees me says something along the lines of "you're huge!" (I am). My stomach and legs itch. My back hurts. I'm having Braxton-Hicks contractions almost all the time. I'm tired, because even with my old standby Tylenol PM, I can't seem to sleep more than 6 hours in a night. I feel queasy some of the time (the doctor says this may mean I'm not drinking enough water- but I'm drinking ALL THE TIME).
The real kicker is that I know I'm having an easy pregnancy. Imagine how whiny I'd be if I'd had some actual complications.
*This, from a scientist who firmly believes in the theory of evolution. When I'm awake at night, tossing and turning because if I stay on one side for more than about 20 minutes my leg hurts, I amuse myself by trying to come up with the selective advantage to the miserableness of the last month of pregnancy. I haven't come up with anything plausible. Anyone else have any ideas?
