okay...so I am 20 years old and my chest size is 36 B. My sis has much fuller bosom and she is only 2 years older than me. I am also a little overweight and I have been working towards getting healthy. My hormonal level has been abnormal due to my weight. My periods have been abnormal. I went to see my gyne who said that I would need reduce weight and she has also put me on a prescription drug which would regulate my period. However, I wasn't able to ask some personal questions like will my breast size change if my periods get regular and my hormones are normal. Or this is the maximum growth? Please let me know if you have had same problem or if you have any idea about breast growth during late teens and early 20s. Thanks
