You know what really pi**es me off, why on earth would anyone ring with a random request like that if they hadn't been told to?!!
its not like you sit there one day and say, "i'll ring and see if there are any beds, there might be a chance they will give me a major abdominal operation just on the off chance!!"
Midwives are soo rude, its extra work for them if you get admitted that why thy are huffing and puffing.
Try and speak to your consultant and if its a no go then pretend you have been having contractions!
