I'm with Intertwined. With a uncomplicated twin pregnancy and a family history of longer gestation, March 1st easy. Which is a good thing! See if you can find a pool to hang out in. And some compression socks. Whatever you need to make these next few weeks as comfortable and bearable as possible.
FWIW - I home induced with castor oil at 39 weeks, and I'm split on whether that was a good idea. I got the home birth I wanted and two healthy babes, but they were on the small side and at least one clearly wanted more time.
Good luck!
