And I 39 weeks and 4 days pregnant how long will it takw labour to start?

It can depend, somewhat, on whether your cervix has starting to show signs of preparing. Even that is not exact. Your cervix could be firm and closed and you might go into labour two days later, for example, or you could walk around a few centimeters dilated for several weeks.

You are at the stage where it could be tonight, it could be in another few weeks.

Try your best to enjoy the last bit of time. Find ways to pamper yourself... spend time with family and friends. It won't be much longer!
