is this really a baby girl?

I just had my gender ultrasound on 14+2 and the specialist told me she is definitely sure it is a girl! I am freakin out as everyone keeps telling me ultrasound might be wrong and there are cases that people find out later they are actually having a boy! I don't mind having any of them but I just started doing shopping and don't wanna return cutest items that I bought lol
