Yea, that seems like a really pretty female. Some breeders will give you a discount on a male if you paid for a male and did not get one in the end, so you can get a boy like you wanted but not have to pay full price for him. At any rate, it may be worth emailing the breeder who sold her to you, just to see what they say. She looks super pretty and pink so I think you've got a gem there even if she isn't a boy.
