0.4% of babies are BBA (born before arrival) so I wouldn't see that as being a likely outcome. It happens sometimes but is rare.

This is based on Victorian Peri-Natal Data collection.
No way! I feel so special now! :P

Were you in labour Scorpio? Or are you still around? If you are, go with your gut perhaps, and you can always call the hospital for some peace of mind, at least if they tell you to stay at home you won't be wondering if you should yet or not.

All the best for whenever it all happens!
