Don't want birth control

Please help!! I haven't gotten my period in three months and I am not pregnant. I know this for a fact since I'm a virgin, and I've always been regular with my period. I also took a hormone test, and it said that my hormones were imbalance. So naturally, the doctor prescribed birth control. The problem is I really don't want to take birth control. It makes me so uneasy, and I've heard bad things about it. I also don't like to introduce chemicals/man made substances to my body. Is there anything I can take that is natural that will restore my hormones and period?
