DD didn't engage til a couple of days before labour started.
It might help your bubs to get into a good position if you straddle your chair, or kneel with your knees as wide apart as possible leaning forward over a lounge chair, or beanbag or fitball, while you're watching telly or on BB It keeps your pelvis nice and open, and if you lean forward, it encourages baby to turn their back to your front. I was advised to do this each day during the week before DD was born and also while in early labour.
All the best - not long to go now!
