The whole date thing is really funny though. Especially if you don't agree with the date your doctor has told you. For example if I think I am only 4 and a bit weeks at the moment, but my doctor tells me I am 5 and a bit (cos I had a really long cycle so they are counting from my last period - even though I know when I conceived) then it means that all the tests which you have to do at a certain time, I will be a week early for. I won't worry too much though, cos my mum said that she predicted different (correct) dates for both myself and my brother. Does anyone else not agree with the date they have been given?
