Baby Ambilobe Chameleon Sexing

Hi,
I bought a very, very young panther chameleon a month or so ago from a breeder with many, many years experience. He assures me that my panther chameleon is male and I have also been advised from others that if he says it is a male, it is a male. My worry being that I cannot see a bulge really yet.
I am not sure how young I picked the chameleon up but I'm guessing about 4 weeks old so is now 8 weeks at a guess.

Should I be concerned as I have paid for a male and I still see no bulge. He/she has a strong white line down the middle of her body too.

What do you guys think?

Here are some more pics:

I am sorry but I think that is a female. You cannot always see a bulge. You have to go by the thinness of the tail and the way the tail is formed after the vent. There is that little indentation which leads me to say female.

Yeah I have to say +1 for girls nite.

I'm sorry but I have to agree as well. You have a very beautiful female!
