Was told I was having a Boy Now a Girl😳😳😳

Soooo today I had an ultrasound at 29 weeks and to my suprise I was told that I am not having a boy as I was told at 12wks and 20 wks but in fact a girl! Although I'm thrilled because my hubby and I already have two boys 7 & 1 I'm extremely confused! Has this ever happened to anyone else before!?
