What could be the cause of hormonal fluctuations, irregular periods, and reproductive problems?

Hello doctor,

I am 21 years old. I have never had periods yet, and I am uncertain about my egg production capabilities. When I was 18 years old, I started taking hormonal birth control to aid my development. Prior to this, I lacked breasts and hips, had a deep voice, and was often mistaken for a man on the phone. Within a year, my breast size increased from an A cup to a D cup, the same as my mother's development at her age. I am questioning whether I might be infertile. I engaged in unprotected sexual intercourse before starting hormonal treatment, yet I did not conceive despite my partner's ejaculation. While on birth control, I have a bleeding episode during the pill-free week, although this is not an authentic period since birth control manipulates the body.

Kindly help.
