Yes, with both my Sons, 1st one was born 20 minutes after being told that i couldn't possibly be in labour, 2nd one arrived 45 minutes after being told that.
With my 2nd child i also went into labour prematurely at 33 weeks and was given a tablet to stop the labour allowing me to carry him for another 3 weeks, i then gave birth at 36 weeks.
My DiL had the same thing, she was told she wasn't in labour, (she was full term and definitely in labour), and then told to "take this pill dear", and just like with me labour stopped for a while, every time her labour pains resumed she was given another pill to take, they did this repeatedly for a full week, when my Grandson was eventually born he had to go into an Incubator as he had been born with a Chest Infection.
