When would you feel confident having a gender scan? The place I went for my reassurance scan do it from 16wk however I have seen where people have been to various places and been told 1 gender to be told opposite at 20wk scan? Last time I waited till 18wk as we were on holiday just before but this time I am desperate to know so counting the days till 16wk but am I taking a huge gamble at 16wl 1day for them to get it right?
