gender

So my fiancé is so sure we are having a girl but ive only had boy dreams and have always felt like its a boy but he says girl so much it makes me second guess myself but We dont find out until the 30th ill be happy no matter what but he already has to girls so i feel like he keeps saying girl so he doesnt let himself down becuz he wants a boy he doesnt want any more babies he said 3 is enough... anyone else been in a similar situation
