I had my first OB appt yesterday (ive been seeing my local Dr beforehand) and when the midwife meausured the fundal height it measured 31 weeks instead of 25.

The baby also measured 2 weeks big on my 21 week U/S and the U/S tech even wrote on the report "Baby is bigger than expected for gestational age".

My LMP was 12th September last year so that would put my EDD at 19th June 2007 BUT my first U/S done at 9w 2d determined the EDD to be at 24th July 2007!! Over a months difference! If I was going by my June EDD I would be 30 weeks along right now which would explain why the baby's meausuring 31 weeks.

Will my OB change the due date at all? I definately FEEL a lot further along than what I am. Has this happened to anyone else?
