I wish more people would answer this thread. We tried to find out the sex at 14w, the tech seemed confident. My doctor saw the pictures & completely disagreed, so we called in for another u/s (4 days later) & that tech said the opp gender, but seemed way less confident. Now we are not finding out the gender officially & planning 99% on a little man because it seems like they don't mess up when they say boy.
Today a fellow mom told me that they had told her that her baby was a girl at her 20 week scan & the baby came out & is a boy!!!!! This is someone who had a baby 4 weeks ago, can you imagine.
