Enlargement B to DD Cup?

In 2 weeks i will be having implants, i have wanted to have this procedure done from about the age of 15 and im now 22, so please no answers saying how horrible fake look and how they are unattractive because me personally doesn't think they are, i think Jordan looks fab so please none of that, i have looked at some older questions and answers regarding this and there was just answer after answer from women saying how fake look horrible and i don't think so, so please none of that. i am booked in to have size D implants on the 14th march and i'm really considering calling the hospital and changing this to DD implants, i feel i am going to regret not going bigger, has anyone been in a similar situation who could give me some good advice, i have thought long and hard about this and just because i feel the need to make my bigger does not make me a horrible person so no abuse please
