On a personal note, I can totally relate. Plus, my second baby was overdue (by 3 weeks!) and I ended up moving things along with castor oil. (#1 was right on time.) I know it can seem endless.
On a professional note, I can also relate. Most of my clients have commented on how endless the last couple of weeks seem. Up to and including all of my friends who are doulas, midwives and childbirth educators. You'd think, what with doing this for a living, that we would be chilled out about the whole thing. Not.
Be careful not to let your impatience or exhaustion dictate your care, i.e. inducing the baby just to end the pregnancy (which can introduce a whole host of problems neither of you need) . Babies generally cook as long as they need to, and there's lots of neurological growth going on inside that we're not privy to.
Take some long walks, write in a journal, talk to supportive women who won't tell you labor horror stories (I can't stand it when women do that), perhaps create something. Spend these last few alone days with your hubby/partner.
In just a short time, you'll begin to feel contractions. And then, shortly, you'll enter the most special of all clubs. Being a mother will change your whole life - nothing else in my life compares to my accomplishments as a wife and mother, as old fashioned as that sounds.
Feel free to PM me if you would like to commiserate more or get a heads up over what to expect once the baby is born. I'm happy to answer any questions you might have. Hey, have you thought of hiring a doula to help you and your husband/partner/SO during the birth? (I just have to put in a plug for doulas whereever I go!
Best of luck,
