Missed Period for 58 Days

Basically I finally went to the gynecologist because I haven’t gotten my period in 2 months (last time I got it was July 9) and I am 19 years old, not sexually active, and have been getting my period for 9 years now. I never missed a period for this long. Always a month but never more. The gyno gave me this dietary supplement called Grapexon and told me to take 2 pills every night. I feel like it’s a bit sus cuz I looked these pills up and apparently they aid with weight loss?? Does anyone know anything about these pills or grape seed extract in general? It also have green tea extract and zinc sulphate
