Just wondering

Last year I was pregnant with twins & swear up & down that they were boys ( didn't get the chance to find out ) this pregnancy I am almost positive it's a girl . I'm only 12w but it's just kinda like a hunch & a feeling that I'm having . 
Does anyone else feel like they are having a certain gender ? 
Since I found out I was pregnant I just get the feeling that it's a girl. Hubby & I don't have any preferences . But I am dead set that this time it's a girl .
