It's certainly a good sign, Bindy, but I don't think it means you'll go early necessarily. Aparently in 1st time pgs babies can be engaged, then not, then engaged, etc. They can move around a bit! Must be nice to feel like everything's in the 'right place' though, IYKWIM! That's great news.
My bub didn't engage until a couple of days before she was born, but she was a week late...
