I was 2cm and 80% effaced at 34 weeks and still baby stayed put. I ended up being induced at 38 weeks for pregnancy induced hypertension. So no way to say if you will go before you due date.
you could go on or around your due date or you may need to be induced! Everyones body is different!! I went in to be induced when i was 3 cm dialated!! Its hard to say..its possible....good luck!!
