I second car girl - I went 2 weeks overdue with my first, and was basically told I had to either go in every day for monitoring (the hospital was over an hour away) or be induced. I was fed up, could't face the travel, so chose the latter.
No need for gory details, but induction definitely not fun - I was left with the distinct impression that DD just didn't feel she was ready to make an appearance, and my labour experience definitely bore that out (no pun intended ). I think with hindsight I'd have pushed back a bit - tried to get monitored at somewhere a bit more local and just hung on in there.
2 other things to bear in mind - firstly is that unless you had a very early scan, dating can easily be a couple of weeks off, so you may not actually physically be overdue (even though mathmatically you are).
Secondly that sizings are often bollocks - I asked whether mine was a huge baby as I felt enormous and was told no, average, if anything a little on the small side. So imagine my shock when I (finally) delivered a 9lb12oz whopper - I'm only 5ft 1 and (was) a size 10... Which deosn't meant o say that yours will be even bigger - just that they really can't tell...
I know (trust me, I KNOW) how fed up you are - how yu're probably getting loads of phone calls to ask if you've had the baby yet ('cause, like, you'd keep it a secret if you had, right?) you feel liek you're going to explode at the seams and you've just had enough already, but I really think it's worth hanging in there if you can... I think it'll lead to a much nicer experience in the long run.
Hang in there, enjoy your last few days of rest and sleep, and try some of those 'home remedies'. Honestly, I don't think any of them make a blind bit of difference, but it gives you something to do... and some can be quite fun. I'd give the castor oil a big skip though... eurghhhhh...
Good luck - you'll get there - so far as I know, no-one's actually ever been pregnant forever, right?
And you're 2cm! Yay! It took me nearly 24 hous of labour to get to 2cms...
