Suggest Remedy To Enhance Size Of Breasts

Hi, I'm a 17yr old female, turning 18 this august. I got my period at 11 1/2 yrs. I have been a 34b cup since then and I have not grown. Everyone in my family has very large breats. My mother is a 38 DD and she got her period at age 9 or 10, and my grandmother is around the same size or a C, but she had aged & her breast size seems to have lessened. My mother's grandma on both father and mother's side have D size breast as well, & their not overweight. Even on my father's side, his mother has D size breast, as well as my cousins, they all have D or DD breast. I am wondering if I am underdeveloped? I was also a vegetarian since the age of 12 but I am currently eating meat again (for about a year now) due to fear of having affected my breast growth. I am wondering if this is the possible cause of why my breast are still 34B & can I ask a doctor for breast enlargement hormones & will it help to make me Dcup or even a big C cup? ~ Alex
