Oh yes yes yes!!!!!
Ha!
Although it wasn't because I was worn out. I felt *FINE*. Really. Totally fine. As a matter of fact the ONLY single reason I stopped teaching step aerobics every week was because I wanted to sleep late (Had to be up at 8:00 on Saturdays for my 9:00 class otherwise.) I still worked out, took my friends boxing class, lifted weights with DH, etc. When DS was 4 days late, DH & I trimmed the tree in the front yard, stacking & chopping wood.
BUT...

You would think people couldn't see me in front of their eyes. They couldn't accept what was in front of them... a very PG, but healthy & physically comfortable lady. (I'm lucky, I didn't even have swelling in the ankles - NOTHING.) Everyone kept saying, "Oh, you must be so sick of being pregnant?" etc. Um, no, I feel GREAT physically! Really!
Then as the due date passed, I started freaking out! I never even had any BH, so I was starting to wonder if my uterus even
worked!

I was terrified of having to be induced, so the pressure of wondering if it would EVER happen got to me. (I had no problems going to 42W, but I know there IS some risk as you pass that.) Hearing ALL.THE.TIME, "Any day now, huh?" or "No Baby yet!? You still PG?" just rubbed salt in my wound.
And THEN there's the whole fun issue of birth discussions.

:

Ya know, "What?! Natural?! Humph... you'll be begging for that epidural!"
Um, yeah, if I were clueless & let them needlessly break my water & give me pitocin - increasing my pain - then let them force me to stay continually hooked up to a monitor & confined to the bed, unable to use natural pain relief techniques like immersion in water... yeah.. if I weren't educated & did it that way, I would be begging for an epidural! 

As I joked, I was
not fit for human contact!
