Am I to young to be having menopause?

I am almost 26 years old. I haven't had a period in over a year. I went to my gyno and all she did was give me meds to start my period back up. 4 days after stopping the meds I had my first period in over a year. However, Its now 2 months later, and I still have no period. I called and filled her in and she offered to put me on Birth control, but due to my heart I can not be on any kind of BC. SO, that was a no go. Then she tells me well maybe you should find another DR. !! WOW....So, Ive been snooping, and I found some signs and symptoms of menopause, and they fit my symptoms PERFECTLY!! Is this possible? Could I be going through premature menopause? I mean seriously is it possible?? Thank you for any help or advice!!
