Soryy...but i have been a Midwife for 20 years and have never bought into the whole 'i never knew i was pregnant' nonsense. I can understanding ,maybe , getting most of the way through...but by 28-30 weeks that sucker is moving! and if you dont think that is weird enough to see a doctor then you need your bumps felt

as for going into labour...well...it hurts, and surely to heavens if you didnt know you where pregnant ,you would be freaked out by labour!
Concealed pregnancy, a whole different ball game. I have had the misfortune to deliver a few babies in A and E that where concealed...but thats more to do with social pressure/fear that actually not knowing your pregnant.
And was this baby 30 weeks...coz again...i have never known a 30 weeker that didnt need some special care, even if it is just help with temperature control or feeding. NEVER!
And whilst i am far from an advocate for the medicalisation of childbirth,and agree that it is very much a 'developed world' phenomonon that childbirth is a medical emergency, any woman stupid enough to labour for 10 hours then give birth down a toilet isnt responsible enough to be a parent.
Just my 2 pence worth
